In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate Dirty Page Table capacity in log_replay copy_lcns In the… (CVE-2026-64432)CVE-2026-64432 0 A vulnerability in the Linux kernel's NTFS3 filesystem driver was resolved involving improper validation of the Dirty Page Table (DPT) capacity during journal replay. Specifically, the log_replay() function could perform an out-of-bounds write to kernel memory when processing crafted NTFS images with manipulated LCN counts. This occurs due to insufficient bounds checking on indices used to copy Logical Cluster Numbers (LCNs) into the DPT, potentially leading to a kernel slab out-of-bounds write at mount time. The issue was fixed by adding validation checks on target VCN deltas and LCN counts against the DPT entry capacity, preventing out-of-bounds memory writes.
