In the Linux kernel, the following vulnerabilities have been resolved: x86/mm/pat: fixed the handling of VMPAT in COW mappings. The handling of VMPAT does not work correctly in COW mappings: the first PTE or, in fact, all PTEs can be replaced during write faults, causing them to point to anonymou...

In the Linux kernel, the following vulnerability has been resolved: xfrm: esp: avoid in-place decrypt on shared skb frags The MSGSPLICEPAGES function can attach pages from a pipe directly to an skb. TCP marks such skbs with SKBFLSHAREDFRAG after skbsplicefromiter, so later processes that may modi...

CVE-2026-72043

A flaw was found in the Linux kernel, specifically affecting the LoongArch architecture when the hardware page table walker PTW is enabled. This vulnerability stems from a missing dirty page tracking mechanism in the ptewrprotect and pmdwrprotect functions, which can lead to incorrect handling of...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix missing dirty page tracking in pte,pmdwrprotect When hardware page table walker PTW is enabled on LoongArch, the CPU may set PAGEDIRTY directly in the page table entry during a write TLB miss, without going through...

CVE-2026-72043

This CVE describes a LoongArch Linux kernel issue where hardware page table walker (PTW) could set only _PAGE_DIRTY in PTE/PMD during a write TLB miss, leaving _PAGE_MODIFIED unchanged. On fork/clone with COW, pte_wrprotect()/pmd_wrprotect() clear _PAGE_WRITE and _PAGE_DIRTY, which could lose the...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix missing dirty page tracking in pte,pmd wrprotect When hardware page table walker PTW is enabled on LoongArch, the CPU may set PAGE DIRTY directly in the page table entry during a write TLB miss, without going throu...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: net/sched: Fixed a issue where partial COW operations by pedit led to corruption of the page cache. tcfpeditact calculates the COW range for skbensurewritable once before the key loop, using tcfpoffmaxhint. However, this hint...

kernel: XFS data corruption using reflink

A flaw was found in the XFS filesystem. A race condition in the copy-on-write mechanism for reflinked files can cause writes to bypass the copy-on-write process and modify shared data blocks directly. As a result, data intended for a private copy may be written to the original shared location,...
