The test procedure is: while true; do jailhouse enable imx8mp.cell jailhouse cell linux xxxx sleep 10 jailhouse cell destroy 1 jailhouse disable sleep 5 done And during the upper test, press keys to the 2nd linux console. When `jailhouse cell destroy 1`, the 2nd linux has no chance to put the uart to a quiese state, so USR1/2 may has pending interrupts. Then when `jailhosue cell linux xx` to start 2nd linux again, the issue trigger. In order to disable irqs before requesting them, both UCR1 and UCR2 irqs should be disabled, so here fix that, disable the Ageing Timer interrupt in UCR2 as UCR1 does. | ||||

| CVE-2023-53798 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ethtool: Fix uninitialized number of lanes It is not possible to set the number of lanes when setting link modes using the legacy IOCTL ethtool interface. Since 'struct ethtool_link_ksettings' is not initialized in this path, drivers receive an uninitialized number of lanes in 'struct ethtool_link_ksettings::lanes'. When this information is later queried from drivers, it results in the ethtool code making decisions based on uninitialized memory, leading to the following KMSAN splat [1]. In practice, this most likely only happens with the tun driver that simply returns whatever it got in the set operation. As far as I can tell, this uninitialized memory is not leaked to user space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in linkmodes_prepare_data(). Fix by initializing the structure in the IOCTL path. Did not find any more call sites that pass an uninitialized structure when calling 'ethtool_ops::set_link_ksettings()'.

| CVE-2025-7647 | 2 Linux, Run-llama | 2 Linux, Llama Index | 2026-04-15 | N/A |
| The llama-index-core package, up to version 0.12.44, contains a vulnerability in the `get_cache_dir()` function where a predictable, hardcoded directory path `/tmp/llama_index` is used on Linux systems without proper security controls. This vulnerability allows attackers on multi-user systems to steal proprietary models, poison cached embeddings, or conduct symlink attacks. The issue affects all Linux deployments where multiple users share the same system. The vulnerability is classified under CWE-379, CWE-377, and CWE-367, indicating insecure temporary file creation and potential race conditions. | ||||
| CVE-2023-53778 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Clean up integer overflow checking in map_user_pages() The encode_dma() function has some validation on in_trans->size but it would be more clear to move those checks to find_and_map_user_pages(). The encode_dma() had two checks: if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size) return -EINVAL; The in_trans->addr variable is the starting address. The in_trans->size variable is the total size of the transfer. The transfer can occur in parts and the resources->xferred_dma_size tracks how many bytes we have already transferred. This patch introduces a new variable "remaining" which represents the amount we want to transfer (in_trans->size) minus the amount we have already transferred (resources->xferred_dma_size). I have modified the check for if in_trans->size is zero to instead check if in_trans->size is less than resources->xferred_dma_size. If we have already transferred more bytes than in_trans->size then there are negative bytes remaining which doesn't make sense. If there are zero bytes remaining to be copied, just return success. The check in encode_dma() checked that "addr + size" could not overflow and barring a driver bug that should work, but it's easier to check if we do this in parts. First check that "in_trans->addr + resources->xferred_dma_size" is safe. Then check that "xfer_start_addr + remaining" is safe. My final concern was that we are dealing with u64 values but on 32bit systems the kmalloc() function will truncate the sizes to 32 bits. So I calculated "total = in_trans->size + offset_in_page(xfer_start_addr);" and returned -EINVAL if it were >= SIZE_MAX. This will not affect 64bit systems. | ||||

| In the Linux kernel, the following vulnerability has been resolved: erofs: kill hooked chains to avoid loops on deduplicated compressed images After heavily stressing EROFS with several images which include a hand-crafted image of repeated patterns for more than 46 days, I found two chains could be linked with each other almost simultaneously and form a loop so that the entire loop won't be submitted. As a consequence, the corresponding file pages will remain locked forever. It can be _only_ observed on data-deduplicated compressed images. For example, consider two chains with five pclusters in total: Chain 1: 2->3->4->5 -- The tail pcluster is 5; Chain 2: 5->1->2 -- The tail pcluster is 2. Chain 2 could link to Chain 1 with pcluster 5; and Chain 1 could link to Chain 2 at the same time with pcluster 2. Since hooked chains are all linked locklessly now, I have no idea how to simply avoid the race. Instead, let's avoid hooked chains completely until I could work out a proper way to fix this and end users finally tell us that it's needed to add it back. Actually, this optimization can be found with multi-threaded workloads (especially even more often on deduplicated compressed images), yet I'm not sure about the overall system impacts of not having this compared with implementation complexity. | ||||

| In the Linux kernel, the following vulnerability has been resolved: regmap-irq: Fix out-of-bounds access when allocating config buffers When allocating the 2D array for handling IRQ type registers in regmap_add_irq_chip_fwnode(), the intent is to allocate a matrix with num_config_bases rows and num_config_regs columns. This is currently handled by allocating a buffer to hold a pointer for each row (i.e. num_config_bases). After that, the logic attempts to allocate the memory required to hold the register configuration for each row. However, instead of doing this allocation for each row (i.e. num_config_bases allocations), the logic erroneously does this allocation num_config_regs number of times. This scenario can lead to out-of-bounds accesses when num_config_regs is greater than num_config_bases. Fix this by updating the terminating condition of the loop that allocates the memory for holding the register configuration to allocate memory only for each row in the matrix. Amit Pundir reported a crash that was occurring on his db845c device due to memory corruption (see "Closes" tag for Amit's report). The KASAN report below helped narrow it down to this issue: [ 14.033877][ T1] ================================================================== [ 14.042507][ T1] BUG: KASAN: invalid-access in regmap_add_irq_chip_fwnode+0x594/0x1364 [ 14.050796][ T1] Write of size 8 at addr 06ffff8081021850 by task init/1 [ 14.242004][ T1] The buggy address belongs to the object at ffffff8081021850 [ 14.242004][ T1] which belongs to the cache kmalloc-8 of size 8 [ 14.255669][ T1] The buggy address is located 0 bytes inside of [ 14.255669][ T1] 8-byte region [ffffff8081021850, ffffff8081021858) | ||||

Make completion statistics an atomic variable to reflect coherent updates to it. This will also avoid load/store tearing logic bug potentially possible by compiler optimizations.

| In the Linux kernel, the following vulnerability has been resolved: dm flakey: don't corrupt the zero page When we need to zero some range on a block device, the function __blkdev_issue_zero_pages submits a write bio with the bio vector pointing to the zero page. If we use dm-flakey with corrupt bio writes option, it will corrupt the content of the zero page which results in crashes of various userspace programs. Glibc assumes that memory returned by mmap is zeroed and it uses it for calloc implementation; if the newly mapped memory is not zeroed, calloc will return non-zeroed memory. Fix this bug by testing if the page is equal to ZERO_PAGE(0) and avoiding the corruption in this case. | ||||

| In the Linux kernel, the following vulnerability has been resolved: refscale: Fix uninitalized use of wait_queue_head_t Running the refscale test occasionally crashes the kernel with the following error: [ 8569.952896] BUG: unable to handle page fault for address: ffffffffffffffe8 [ 8569.952900] #PF: supervisor read access in kernel mode [ 8569.952902] #PF: error_code(0x0000) - not-present page [ 8569.952904] PGD c4b048067 P4D c4b049067 PUD c4b04b067 PMD 0 [ 8569.952910] Oops: 0000 [#1] PREEMPT_RT SMP NOPTI [ 8569.952916] Hardware name: Dell Inc. PowerEdge R750/0WMWCR, BIOS 1.2.4 05/28/2021 [ 8569.952917] RIP: 0010:prepare_to_wait_event+0x101/0x190 : [ 8569.952940] Call Trace: [ 8569.952941] <TASK> [ 8569.952944] ref_scale_reader+0x380/0x4a0 [refscale] [ 8569.952959] kthread+0x10e/0x130 [ 8569.952966] ret_from_fork+0x1f/0x30 [ 8569.952973] </TASK> The likely cause is that init_waitqueue_head() is called after the call to the torture_create_kthread() function that creates the ref_scale_reader kthread. Although this init_waitqueue_head() call will very likely complete before this kthread is created and starts running, it is possible that the calling kthread will be delayed between the calls to torture_create_kthread() and init_waitqueue_head(). In this case, the new kthread will use the waitqueue head before it is properly initialized, which is not good for the kernel's health and well-being. The above crash happened here: static inline void __add_wait_queue(...) { : if (!(wq->flags & WQ_FLAG_PRIORITY)) <=== Crash here The offset of flags from list_head entry in wait_queue_entry is -0x18. If reader_tasks[i].wq.head.next is NULL as allocated reader_task structure is zero initialized, the instruction will try to access address 0xffffffffffffffe8, which is exactly the fault address listed above. This commit therefore invokes init_waitqueue_head() before creating the kthread. | ||||

So provide for a synchronous registration path to preclude this scenario. | ||||

| In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix out-of-bounds read When preparing an AER-CTR request, the driver copies the key provided by the user into a data structure that is accessible by the firmware. If the target device is QAT GEN4, the key size is rounded up by 16 since a rounded up size is expected by the device. If the key size is rounded up before the copy, the size used for copying the key might be bigger than the size of the region containing the key, causing an out-of-bounds read. Fix by doing the copy first and then update the keylen. This is to fix the following warning reported by KASAN: [ 138.150574] BUG: KASAN: global-out-of-bounds in qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.150641] Read of size 32 at addr ffffffff88c402c0 by task cryptomgr_test/2340 [ 138.150651] CPU: 15 PID: 2340 Comm: cryptomgr_test Not tainted 6.2.0-rc1+ #45 [ 138.150659] Hardware name: Intel Corporation ArcherCity/ArcherCity, BIOS EGSDCRB1.86B.0087.D13.2208261706 08/26/2022 [ 138.150663] Call Trace: [ 138.150668] <TASK> [ 138.150922] kasan_check_range+0x13a/0x1c0 [ 138.150931] memcpy+0x1f/0x60 [ 138.150940] qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.151006] qat_alg_skcipher_init_sessions+0xc1/0x240 [intel_qat] [ 138.151073] crypto_skcipher_setkey+0x82/0x160 [ 138.151085] ? prepare_keybuf+0xa2/0xd0 [ 138.151095] test_skcipher_vec_cfg+0x2b8/0x800 | ||||
