CVE-2026-89617

A vulnerability in the Linux kernel NTFS3 filesystem driver (fs/ntfs3) allows a local attacker to craft a malicious NTFS log file where a tampered lcns_follow field in a DIR_PAGE_ENTRY causes an out-of-bounds write during log replay. The root cause is that check_rstbl() validates table bookkeepin...

CVE-2026-72132

A flaw was found in the Linux kernel's Network File System NFS component. The nfsfoliomarkunstable and nfsfolioclearcommit functions incorrectly account for unstable writes, charging the full folio size for each sub-folio request. This inflated accounting can push the system's dirty page threshol...

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...

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...
