| In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: Use the correct type in nvidia_smmu_context_fault() This was missed because of the function pointer indirection. nvidia_smmu_context_fault() is also installed as a irq function, and the 'void *' was changed to a struct arm_smmu_domain. Since the iommu_domain is embedded at a non-zero offset this causes nvidia_smmu_context_fault() to miscompute the offset. Fixup the types.

| In the Linux kernel, the following vulnerability has been resolved: net: fix out-of-bounds access in ops_init net_alloc_generic is called by net_alloc, which is called without any locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It is read twice, first to allocate an array, then to set s.len, which is later used to limit the bounds of the array access. It is possible that the array is allocated and another thread is registering a new pernet ops, increments max_gen_ptrs, which is then used to set s.len with a larger than allocated length for the variable array. Fix it by reading max_gen_ptrs only once in net_alloc_generic. If max_gen_ptrs is later incremented, it will be caught in net_assign_generic. | ||||

| In the Linux kernel, the following vulnerability has been resolved: i40e: fix vf may be used uninitialized in this function warning To fix the regression introduced by commit 52424f974bc5, which causes servers hang in very hard to reproduce conditions with resets races. Using two sources for the information is the root cause. In this function before the fix bumping v didn't mean bumping vf pointer. But the code used this variables interchangeably, so stale vf could point to different/not intended vf. Remove redundant "v" variable and iterate via single VF pointer across whole function instead to guarantee VF pointer validity. | ||||

The code was indexing entry[] by only the register address, leading to an out-of-bounds access that copied some part of the kernel memory over the cache contents. This bug was not detected by the regmap KUnit test because it only tests with a block of registers starting at 0, so mas.index == 0. | ||||

| In the Linux kernel, the following vulnerability has been resolved: tty: n_gsm: fix possible out-of-bounds in gsm0_receive() Assuming the following: - side A configures the n_gsm in basic option mode - side B sends the header of a basic option mode frame with data length 1 - side A switches to advanced option mode - side B sends 2 data bytes which exceeds gsm->len Reason: gsm->len is not used in advanced option mode. - side A switches to basic option mode - side B keeps sending until gsm0_receive() writes past gsm->buf Reason: Neither gsm->state nor gsm->len have been reset after reconfiguration. Fix this by changing gsm->count to gsm->len comparison from equal to less than. Also add upper limit checks against the constant MAX_MRU in gsm0_receive() and gsm1_receive() to harden against memory corruption of gsm->len and gsm->mru. All other checks remain as we still need to limit the data according to the user configuration and actual payload size. | ||||

| CVE-2024-36007 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix warning during rehash As previously explained, the rehash delayed work migrates filters from one region to another. This is done by iterating over all chunks (all the filters with the same priority) in the region and in each chunk iterating over all the filters. When the work runs out of credits it stores the current chunk and entry as markers in the per-work context so that it would know where to resume the migration from the next time the work is scheduled. Upon error, the chunk marker is reset to NULL, but without resetting the entry markers despite being relative to it. This can result in migration being resumed from an entry that does not belong to the chunk being migrated. In turn, this will eventually lead to a chunk being iterated over as if it is an entry. Because of how the two structures happen to be defined, this does not lead to KASAN splats, but to warnings such as [1]. Fix by creating a helper that resets all the markers and call it from all the places the currently only reset the chunk marker. For good measures also call it when starting a completely new rehash. Add a warning to avoid future cases.

| CVE-2024-35994 | 1 Linux | 1 Linux Kernel | 2026-08-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: uefisecapp: Fix memory related IO errors and crashes It turns out that while the QSEECOM APP_SEND command has specific fields for request and response buffers, uefisecapp expects them both to be in a single memory region. Failure to adhere to this has (so far) resulted in either no response being written to the response buffer (causing an EIO to be emitted down the line), the SCM call to fail with EINVAL (i.e., directly from TZ/firmware), or the device to be hard-reset. While this issue can be triggered deterministically, in the current form it seems to happen rather sporadically (which is why it has gone unnoticed during earlier testing). This is likely due to the two kzalloc() calls (for request and response) being directly after each other. Which means that those likely return consecutive regions most of the time, especially when not much else is going on in the system. Fix this by allocating a single memory region for both request and response buffers, properly aligning both structs inside it. This unfortunately also means that the qcom_scm_qseecom_app_send() interface needs to be restructured, as it should no longer map the DMA regions separately. Therefore, move the responsibility of DMA allocation (or mapping) to the caller. | ||||

| In the Linux kernel, the following vulnerability has been resolved: mm: turn folio_test_hugetlb into a PageType The current folio_test_hugetlb() can be fooled by a concurrent folio split into returning true for a folio which has never belonged to hugetlbfs. This can't happen if the caller holds a refcount on it, but we have a few places (memory-failure, compaction, procfs) which do not and should not take a speculative reference. Since hugetlb pages do not use individual page mapcounts (they are always fully mapped and use the entire_mapcount field to record the number of mappings), the PageType field is available now that page_mapcount() ignores the value in this field. In compaction and with CONFIG_DEBUG_VM enabled, the current implementation can result in an oops, as reported by Luis. This happens since 9c5ccf2db04b ("mm: remove HUGETLB_PAGE_DTOR") effectively added some VM_BUG_ON() checks in the PageHuge() testing path. [willy@infradead.org: update vmcoreinfo] | ||||

| In the Linux kernel, the following vulnerability has been resolved: riscv: Fix loading 64-bit NOMMU kernels past the start of RAM commit 3335068f8721 ("riscv: Use PUD/P4D/PGD pages for the linear mapping") added logic to allow using RAM below the kernel load address. However, this does not work for NOMMU, where PAGE_OFFSET is fixed to the kernel load address. Since that range of memory corresponds to PFNs below ARCH_PFN_OFFSET, mm initialization runs off the beginning of mem_map and corrupts adjacent kernel memory. Fix this by restoring the previous behavior for NOMMU kernels. | ||||
