CVE-2025-37931

CVE-2025-37931 (btrfs) affects the Linux kernel’s btrfs metadata write path. The issue arises when writing subpage extent buffers (EBs) with a 64k page size, 16k nodsz, and a 4k sectorsize, where the bitmap addressing is based on sectors, yielding 4 bits per node. If a dirty range is found, the c...
