| CVE-2025-2559 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-05-06 | 4.9 Medium |
| A flaw was found in Keycloak. When the configuration uses JWT tokens for authentication, the tokens are cached until expiration. If a client uses JWT tokens with an excessively long expiration time, for example, 24 or 48 hours, the cache can grow indefinitely, leading to an OutOfMemoryError. This issue could result in a denial of service condition, preventing legitimate users from accessing the system. | ||||
| CVE-2025-1391 | 1 Redhat | 1 Build Keycloak | 2026-05-06 | 5.4 Medium |
| A flaw was found in the Keycloak organization feature, which allows the incorrect assignment of an organization to a user if their username or email matches the organization’s domain pattern. This issue occurs at the mapper level, leading to misrepresentation in tokens. If an application relies on these claims for authorization, it may incorrectly assume a user belongs to an organization they are not a member of, potentially granting unauthorized access or privileges. | ||||
| CVE-2024-10270 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2026-05-06 | 6.5 Medium |
| A vulnerability was found in the Keycloak-services package. If untrusted data is passed to the SearchQueryUtils method, it could lead to a denial of service (DoS) scenario by exhausting system resources due to a Regex complexity. | ||||
| CVE-2025-1634 | 1 Redhat | 3 Amq Streams, Camel Quarkus, Quarkus | 2026-05-06 | 7.5 High |
| A flaw was found in the quarkus-resteasy extension, which causes memory leaks when client requests with low timeouts are made. If a client request times out, a buffer is not released correctly, leading to increased memory usage and eventual application crash due to OutOfMemoryError. | ||||
| CVE-2024-12582 | 1 Redhat | 1 Service Interconnect | 2026-05-06 | 7.1 High |
| A flaw was found in the skupper console, a read-only interface that renders cluster network, traffic details, and metrics for a network application that a user sets up across a hybrid multi-cloud environment. When the default authentication method is used, a random password is generated for the "admin" user and is persisted in either a Kubernetes secret or a podman volume in a plaintext file. This authentication method can be manipulated by an attacker, leading to the reading of any user-readable file in the container filesystem, directly impacting data confidentiality. Additionally, the attacker may induce skupper to read extremely large files into memory, resulting in resource exhaustion and a denial of service attack. | ||||

| In the Linux kernel, the following vulnerability has been resolved: dcache: Limit the minimal number of bucket to two There is an OOB read problem on dentry_hashtable when user sets 'dhash_entries=1': BUG: unable to handle page fault for address: ffff888b30b774b0 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page Oops: Oops: 0000 [#1] SMP PTI RIP: 0010:__d_lookup+0x56/0x120 Call Trace: d_lookup.cold+0x16/0x5d lookup_dcache+0x27/0xf0 lookup_one_qstr_excl+0x2a/0x180 start_dirop+0x55/0xa0 simple_start_creating+0x8d/0xa0 debugfs_start_creating+0x8c/0x180 debugfs_create_dir+0x1d/0x1c0 pinctrl_init+0x6d/0x140 do_one_initcall+0x6d/0x3d0 kernel_init_freeable+0x39f/0x460 kernel_init+0x2a/0x260 There will be only one bucket in dentry_hashtable when dhash_entries is set as one, and d_hash_shift is calculated as 32 by dcache_init(). Then, following process will access more than one buckets(which memory region is not allocated) in dentry_hashtable: d_lookup b = d_hash(hash) dentry_hashtable + ((u32)hashlen >> d_hash_shift) // The C standard defines the behavior of right shift amounts // exceeding the bit width of the operand as undefined.

| In the Linux kernel, the following vulnerability has been resolved: x86-64: rename misleadingly named '__copy_user_nocache()' function This function was a masterclass in bad naming, for various historical reasons. It claimed to be a non-cached user copy. It is literally _neither_ of those things. It's a specialty memory copy routine that uses non-temporal stores for the destination (but not the source), and that does exception handling for both source and destination accesses. Also note that while it works for unaligned targets, any unaligned parts (whether at beginning or end) will not use non-temporal stores, since only words and quadwords can be non-temporal on x86. The exception handling means that it _can_ be used for user space accesses, but not on its own - it needs all the normal "start user space access" logic around it. But typically the user space access would be the source, not the non-temporal destination. That was the original intention of this, where the destination was some fragile persistent memory target that needed non-temporal stores in order to catch machine check exceptions synchronously and deal with them gracefully. Thus that non-descriptive name: one use case was to copy from user space into a non-cached kernel buffer. However, the existing users are a mix of that intended use-case, and a couple of random drivers that just did this as a performance tweak. Some of those random drivers then actively misused the user copying version (with STAC/CLAC and all) to do kernel copies without ever even caring about the exception handling, _just_ for the non-temporal destination. Rename it as a first small step to actually make it halfway sane, and change the prototype to be more normal: it doesn't take a user pointer unless the caller has done the proper conversion, and the argument size is the full size_t (it still won't actually copy more than 4GB in one go, but there's also no reason to silently truncate the size argument in the caller). Finally, use this now sanely named function in the NTB code, which mis-used a user copy version (with STAC/CLAC and all) of this interface despite it not actually being a user copy at all. | ||||
| CVE-2025-71273 | 1 Linux | 1 Linux Kernel | 2026-05-06 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Use devm_kmemdup() in rtw_set_supported_band() Simplify the code by using device managed memory allocations. This also fixes a memory leak in rtw_register_hw(). The supported bands were not freed in the error path. Copied from commit 145df52a8671 ("wifi: rtw89: Convert rtw89_core_set_supported_band to use devm_*"). | ||||
| CVE-2026-43128 | 1 Linux | 1 Linux Kernel | 2026-05-06 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Fix double dma_buf_unpin in failure path In ib_umem_dmabuf_get_pinned_with_dma_device(), the call to ib_umem_dmabuf_map_pages() can fail. If this occurs, the dmabuf is immediately unpinned but the umem_dmabuf->pinned flag is still set. Then, when ib_umem_release() is called, it calls ib_umem_dmabuf_revoke() which will call dma_buf_unpin() again. Fix this by removing the immediate unpin upon failure and just let the ib_umem_release/revoke path handle it. This also ensures the proper unmap-unpin unwind ordering if the dmabuf_map_pages call happened to fail due to dma_resv_wait_timeout (and therefore has a non-NULL umem_dmabuf->sgt). | ||||
| CVE-2026-43166 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: erofs: fix interlaced plain identification for encoded extents Only plain data whose start position and on-disk physical length are both aligned to the block size should be classified as interlaced plain extents. Otherwise, it must be treated as shifted plain extents. This issue was found by syzbot using a crafted compressed image containing plain extents with unaligned physical lengths, which can cause OOB read in z_erofs_transform_plain(). | ||||
| CVE-2026-43174 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: io_uring/zcrx: fix post open error handling Closing a queue doesn't guarantee that all associated page pools are terminated right away, let the refcounting do the work instead of releasing the zcrx ctx directly. | ||||
| CVE-2026-43177 | 1 Linux | 1 Linux Kernel | 2026-05-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: media: ipu6: Fix RPM reference leak in probe error paths Several error paths in ipu6_pci_probe() were jumping directly to out_ipu6_bus_del_devices without releasing the runtime PM reference. Add pm_runtime_put_sync() before cleaning up other resources. | ||||
| CVE-2026-43255 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: fix WARNING in usb_tx_block The function usb_tx_block() submits cardp->tx_urb without ensuring that any previous transmission on this URB has completed. If a second call occurs while the URB is still active (e.g. during rapid firmware loading), usb_submit_urb() detects the active state and triggers a warning: 'URB submitted while active'. Fix this by enforcing serialization: call usb_kill_urb() before submitting the new request. This ensures the URB is idle and safe to reuse. | ||||
| CVE-2026-43258 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: alpha: fix user-space corruption during memory compaction Alpha systems can suffer sporadic user-space crashes and heap corruption when memory compaction is enabled. Symptoms include SIGSEGV, glibc allocator failures (e.g. "unaligned tcache chunk"), and compiler internal errors. The failures disappear when compaction is disabled or when using global TLB invalidation. The root cause is insufficient TLB shootdown during page migration. Alpha relies on ASN-based MM context rollover for instruction cache coherency, but this alone is not sufficient to prevent stale data or instruction translations from surviving migration. Fix this by introducing a migration-specific helper that combines: - MM context invalidation (ASN rollover), - immediate per-CPU TLB invalidation (TBI), - synchronous cross-CPU shootdown when required. The helper is used only by migration/compaction paths to avoid changing global TLB semantics. Additionally, update flush_tlb_other(), pte_clear(), to use READ_ONCE()/WRITE_ONCE() for correct SMP memory ordering. This fixes observed crashes on both UP and SMP Alpha systems. | ||||
| CVE-2026-43263 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix Null reference while testing fluster When multi instances are created/destroyed, many interrupts happens and structures for decoder are removed. "struct vpu_instance" this structure is shared for all flow in the decoder, so if the structure is not protected by lock, Null dereference could happens sometimes. IRQ Handler was spilt to two phases and Lock was added as well. | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/atmel-hlcdc: fix memory leak from the atomic_destroy_state callback After several commits, the slab memory increases. Some drm_crtc_commit objects are not freed. The atomic_destroy_state callback only put the framebuffer. Use the __drm_atomic_helper_plane_destroy_state() function to put all the objects that are no longer needed. It has been seen after hours of usage of a graphics application or using kmemleak: unreferenced object 0xc63a6580 (size 64): comm "egt_basic", pid 171, jiffies 4294940784 hex dump (first 32 bytes): 40 50 34 c5 01 00 00 00 ff ff ff ff 8c 65 3a c6 @P4..........e:. 8c 65 3a c6 ff ff ff ff 98 65 3a c6 98 65 3a c6 .e:......e:..e:. backtrace (crc c25aa925): kmemleak_alloc+0x34/0x3c __kmalloc_cache_noprof+0x150/0x1a4 drm_atomic_helper_setup_commit+0x1e8/0x7bc drm_atomic_helper_commit+0x3c/0x15c drm_atomic_commit+0xc0/0xf4 drm_atomic_helper_set_config+0x84/0xb8 drm_mode_setcrtc+0x32c/0x810 drm_ioctl+0x20c/0x488 sys_ioctl+0x14c/0xc20 ret_fast_syscall+0x0/0x54 | ||||
| CVE-2026-43270 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: mtk-mdp: Fix a reference leak bug in mtk_mdp_remove() In mtk_mdp_probe(), vpu_get_plat_device() increases the reference count of the returned platform device. Add platform_device_put() to prevent reference leak. | ||||
| CVE-2026-43275 | 1 Linux | 1 Linux Kernel | 2026-05-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Flush exception handling work when RPM level is zero Ensure that the exception event handling work is explicitly flushed during suspend when the runtime power management level is set to UFS_PM_LVL_0. When the RPM level is zero, the device power mode and link state both remain active. Previously, the UFS core driver bypassed flushing exception event handling jobs in this configuration. This created a race condition where the driver could attempt to access the host controller to handle an exception after the system had already entered a deep power-down state, resulting in a system crash. Explicitly flush this work and disable auto BKOPs before the suspend callback proceeds. This guarantees that pending exception tasks complete and prevents illegal hardware access during the power-down sequence. | ||||
| CVE-2026-43190 | 1 Linux | 1 Linux Kernel | 2026-05-06 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: xt_tcpmss: check remaining length before reading optlen Quoting reporter: In net/netfilter/xt_tcpmss.c (lines 53-68), the TCP option parser reads op[i+1] directly without validating the remaining option length. If the last byte of the option field is not EOL/NOP (0/1), the code attempts to index op[i+1]. In the case where i + 1 == optlen, this causes an out-of-bounds read, accessing memory past the optlen boundary (either reading beyond the stack buffer _opt or the following payload). | ||||
| CVE-2026-43192 | 1 Linux | 1 Linux Kernel | 2026-05-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm mpath: Add missing dm_put_device when failing to get scsi dh name When commit fd81bc5cca8f ("scsi: device_handler: Return error pointer in scsi_dh_attached_handler_name()") added code to fail parsing the path if scsi_dh_attached_handler_name() failed with -ENOMEM, it didn't clean up the reference to the path device that had just been taken. Fix this, and steamline the error paths of parse_path() a little. | ||||
