CVE-2026-53320

A flaw was found in the Linux kernel's nilfs2 filesystem. A local attacker could exploit this vulnerability by sending a specially crafted input/output control ioctl request to the nilfsioctlmarkblocksdirty function. By providing a zero block number, the attacker can bypass a critical dead block...

CVE-2026-46124

CVE-2026-46124 affects the Linux kernel isofs filesystem. The vulnerability arises because isofs_fh_to_dentry/isofs_fh_to_parent pass an attacker-controlled block number from an NFS file handle to isofs_export_iget(), which only rejects block == 0 before calling isofs_iget and sb_bread. A crafted...
