CVE-2026-53320

CVE-2026-53320 : In the Linux kernel’s nilfs2 code, a vulnerability exists in nilfs_ioctl_mark_blocks_dirty() where bd_oblocknr may be 0. The function uses bd_oblocknr to detect dead blocks by comparing it to the current bd_blocknr; if they differ, the block is skipped as dead. Since block 0 stor...
