CVE-2026-23416
A flaw was found in the Linux kernel. An issue in the memory management mm/mseal component, specifically during the merging of Virtual Memory Areas VMAs, could lead to incorrect updates of VMA end pointers. This could result in stale memory pointers and incorrect starting points for subsequent...
EUVD-2026-18198
In the Linux kernel, the following vulnerability has been resolved: mm/mseal: update VMA end correctly on merge Previously we stored the end of the current VMA in currend, and then upon iterating to the next VMA updated currstart to currend to advance to the next VMA. However, this doesn't take...

CVE-2026-23416
The CVE-2026-23416 issue affects the Linux kernel (mm/mseal) where vm_area_struct end handling could become stale during VMA merges. The root cause is curr_end not staying in sync when a VMA is updated via vma_modify_flags(), leading to an incorrect curr_start on the next iteration. The fix uncon...

However, this doesn't tak...
CVE-2025-68329
The CVE-2025-68329 entry documents a Linux kernel issue in tracing: when a VMA is split, the kernel could invoke ring_buffer_unmap multiple times (due to multiple vm_ops->close calls) while ring_buffer_map was called once, causing ring_buffer_unmap to return -ENODEV and triggering a WARN_ON. T...
CVE-2025-68329 tracing: Fix WARN_ON in tracing_buffers_mmap_close for split VMAs
In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose for split VMAs When a VMA is split e.g., by partial munmap or MAPFIXED, the kernel calls vmops-close on each portion. For trace buffer mappings, this results in ringbufferunmap being...
AZL-72419 CVE-2025-68211 affecting package kernel for versions less than 6.6.121.1-1
In the Linux kernel, the following vulnerability has been resolved: ksm: use range-walk function to jump over holes in scangetnextrmapitem Currently, scangetnextrmapitem walks every page address in a VMA to locate mergeable pages. This becomes highly inefficient when scanning large virtual memory...

CVE-2025-68211
CVE-2025-68211 (Linux kernel, KSM) is addressed by a patch that changes scan_get_next_rmap_item from per-address walking to a range walk using walk_page_range, allowing KSMD to skip unmapped holes in large VMAs. The fix targets inefficiency where KSMD would otherwise scan vast address spaces with...
