CVE-2026-97533

A flaw was found in the Linux kernel's x86 Page Attribute Table PAT memory management subsystem. A race condition occurs when memory attributes are changed concurrently with page table collapse operations, allowing the kernel to access memory after it has been freed. A local user could exploit th...

PT-2026-94864

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the x86 memory management PAT Page Attribute Table implementation. The problem occurs when loading and unloading modules concurrently on multiple CPUs...

UBUNTU-CVE-2026-46309

In the Linux kernel, the following vulnerability has been resolved: drm/xe/uapi: Reject cohnone PAT index for CPU cached memory in madvise Add validation in xevmmadviseioctl to reject PAT indices with XECOHNONE coherency mode when applied to CPU cached memory. Using cohnone with CPU cached buffer...

kernel: x86/mm/pat: fix VM_PAT handling in COW mappings

CVE-2024-35877 pertains to a flaw in the Linux kernel's handling of Page Attribute Table PAT settings during Copy-On-Write COW operations. When a write operation triggers a COW event, the kernel may replace the original page table entries PTEs with anonymous folios. This replacement disrupts the...
