| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix exclusive map memory leak When excl_prog_hash is 0 and excl_prog_hash_size is non-zero, the map also needs to be freed. Otherwise, the map memory will not be reclaimed, just like the memory leak problem reported by syzbot [1]. syzbot reported: BUG: memory leak backtrace (crc 7b9fb9b4): map_create+0x322/0x11e0 kernel/bpf/syscall.c:1512 __sys_bpf+0x3556/0x3610 kernel/bpf/syscall.c:6131 | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/xe: Limit num_syncs to prevent oversized allocations The exec and vm_bind ioctl allow userspace to specify an arbitrary num_syncs value. Without bounds checking, a very large num_syncs can force an excessively large allocation, leading to kernel warnings from the page allocator as below. Introduce DRM_XE_MAX_SYNCS (set to 1024) and reject any request exceeding this limit.

| CVE-2025-40175 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: idpf: cleanup remaining SKBs in PTP flows When the driver requests Tx timestamp value, one of the first steps is to clone SKB using skb_get. It increases the reference counter for that SKB to prevent unexpected freeing by another component. However, there may be a case where the index is requested, SKB is assigned and never consumed by PTP flows - for example due to reset during running PTP apps. Add a check in release timestamping function to verify if the SKB assigned to Tx timestamp latch was freed, and release remaining SKBs. | ||||
| CVE-2025-40179 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: ext4: verify orphan file size is not too big In principle orphan file can be arbitrarily large. However orphan replay needs to traverse it all and we also pin all its buffers in memory. Thus filesystems with absurdly large orphan files can lead to big amounts of memory consumed. Limit orphan file size to a sane value and also use kvmalloc() for allocating array of block descriptor structures to avoid large order allocations for sane but large orphan files. | ||||

| CVE-2025-68350 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: exfat: fix divide-by-zero in exfat_allocate_bitmap The variable max_ra_count can be 0 in exfat_allocate_bitmap(), which causes a divide-by-zero error in the subsequent modulo operation (i % max_ra_count), leading to a system crash. When max_ra_count is 0, it means that readahead is not used. This patch load the bitmap without readahead. | ||||

| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix debug checking for np-guests using huge mappings When running with transparent huge pages and CONFIG_NVHE_EL2_DEBUG then the debug checking in assert_host_shared_guest() fails on the launch of an np-guest. This WARN_ON() causes a panic and generates the stack below. In __pkvm_host_relax_perms_guest() the debug checking assumes the mapping is a single page but it may be a block map. Update the checking so that the size is not checked and just assumes the correct size. While we're here make the same fix in __pkvm_host_mkyoung_guest().

| CVE-2023-54097 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: regulator: stm32-pwr: fix of_iomap leak Smatch reports: drivers/regulator/stm32-pwr.c:166 stm32_pwr_regulator_probe() warn: 'base' from of_iomap() not released on lines: 151,166. In stm32_pwr_regulator_probe(), base is not released when devm_kzalloc() fails to allocate memory or devm_regulator_register() fails to register a new regulator device, which may cause a leak. To fix this issue, replace of_iomap() with devm_platform_ioremap_resource(). devm_platform_ioremap_resource() is a specialized function for platform devices. It allows 'base' to be automatically released whether the probe function succeeds or fails. Besides, use IS_ERR(base) instead of !base as the return value of devm_platform_ioremap_resource() can either be a pointer to the remapped memory or an ERR_PTR() encoded error code if the operation fails. | ||||

| In the Linux kernel, the following vulnerability has been resolved: block: fix race between wbt_enable_default and IO submission When wbt_enable_default() is moved out of queue freezing in elevator_change(), it can cause the wbt inflight counter to become negative (-1), leading to hung tasks in the writeback path. Tasks get stuck in wbt_wait() because the counter is in an inconsistent state. The issue occurs because wbt_enable_default() could race with IO submission, allowing the counter to be decremented before proper initialization. This manifests as: rq_wait[0]: inflight: -1 has_waiters: True rwb_enabled() checks the state, which can be updated exactly between wbt_wait() (rq_qos_throttle()) and wbt_track()(rq_qos_track()), then the inflight counter will become negative. And results in hung task warnings like: task:kworker/u24:39 state:D stack:0 pid:14767 Call Trace: rq_qos_wait+0xb4/0x150 wbt_wait+0xa9/0x100 __rq_qos_throttle+0x24/0x40 blk_mq_submit_bio+0x672/0x7b0 ... Fix this by: 1. Splitting wbt_enable_default() into: - __wbt_enable_default(): Returns true if wbt_init() should be called - wbt_enable_default(): Wrapper for existing callers (no init) - wbt_init_enable_default(): New function that checks and inits WBT 2. Using wbt_init_enable_default() in blk_register_queue() to ensure proper initialization during queue registration 3. Move wbt_init() out of wbt_enable_default() which is only for enabling disabled wbt from bfq and iocost, and wbt_init() isn't needed. Then the original lock warning can be avoided. 4. Removing the ELEVATOR_FLAG_ENABLE_WBT_ON_EXIT flag and its handling code since it's no longer needed This ensures WBT is properly initialized before any IO can be submitted, preventing the counter from going negative. | ||||
| CVE-2023-53834 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: iio: adc: ina2xx: avoid NULL pointer dereference on OF device match The affected lines were resulting in a NULL pointer dereference on our platform because the device tree contained the following list of compatible strings: power-sensor@40 { compatible = "ti,ina232", "ti,ina231"; ... }; Since the driver doesn't declare a compatible string "ti,ina232", the OF matching succeeds on "ti,ina231". But the I2C device ID info is populated via the first compatible string, cf. modalias population in of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy I2C device ID table either, the struct i2c_device_id *id pointer in the probe function is NULL. Fix this by using the already populated type variable instead, which points to the proper driver data. Since the name is also wanted, add a generic one to the ina2xx_config table. | ||||

| In the Linux kernel, the following vulnerability has been resolved: dmaengine: ptdma: check for null desc before calling pt_cmd_callback Resolves a panic that can occur on AMD systems, typically during host shutdown, after the PTDMA driver had been exercised. The issue was the pt_issue_pending() function is mistakenly assuming that there will be at least one descriptor in the Submitted queue when the function is called. However, it is possible that both the Submitted and Issued queues could be empty, which could result in pt_cmd_callback() being mistakenly called with a NULL pointer. Ref: Bugzilla Bug 216856. | ||||

| In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/qm - request reserved interrupt for virtual function The device interrupt vector 3 is an error interrupt for physical function and a reserved interrupt for virtual function. However, the driver has not registered the reserved interrupt for virtual function. When allocating interrupts, the number of interrupts is allocated based on powers of two, which includes this interrupt. When the system enables GICv4 and the virtual function passthrough to the virtual machine, releasing the interrupt in the driver triggers a warning. The WARNING report is: WARNING: CPU: 62 PID: 14889 at arch/arm64/kvm/vgic/vgic-its.c:852 its_free_ite+0x94/0xb4 Therefore, register a reserved interrupt for VF and set the IRQF_NO_AUTOEN flag to avoid that warning. | ||||

| In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix DMA transfer direction When CONFIG_DMA_API_DEBUG is selected, while running the crypto self test on the QAT crypto algorithms, the function add_dma_entry() reports a warning similar to the one below, saying that overlapping mappings are not supported. This occurs in tests where the input and the output scatter list point to the same buffers (i.e. two different scatter lists which point to the same chunks of memory). The logic that implements the mapping uses the flag DMA_BIDIRECTIONAL for both the input and the output scatter lists which leads to overlapped write mappings. These are not supported by the DMA layer. Fix by specifying the correct DMA transfer directions when mapping buffers. For in-place operations where the input scatter list matches the output scatter list, buffers are mapped once with DMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flag DMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE. Overlapping a read mapping with a write mapping is a valid case in dma-coherent devices like QAT. The function that frees and unmaps the buffers, qat_alg_free_bufl() has been changed accordingly to the changes to the mapping function.

| CVE-2022-50760 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios() As comment of pci_get_class() says, it returns a pci_device with its refcount increased and decreased the refcount for the input parameter @from if it is not NULL. If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we need to call pci_dev_put() to decrease the refcount. Add the missing pci_dev_put() to avoid refcount leak. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix double unregister of HCA_PORTS component Clear hca_devcom_comp in device's private data after unregistering it in LAG teardown. Otherwise a slightly lagging second pass through mlx5_unload_one() might try to unregister it again and trip over use-after-free. On s390 almost all PCI level recovery events trigger two passes through mxl5_unload_one() - one through the poll_health() method and one through mlx5_pci_err_detected() as callback from generic PCI error recovery. While testing PCI error recovery paths with more kernel debug features enabled, this issue reproducibly led to kernel panics with the following call chain: Unable to handle kernel pointer dereference in virtual kernel address space Failing address: 6b6b6b6b6b6b6000 TEID: 6b6b6b6b6b6b6803 ESOP-2 FSI Fault in home space mode while using kernel ASCE.
