CVE-2026-64296

The CVE concerns the Linux kernel exFAT driver: in exfat_find_dir_entry(), processing directory NAME entries (TYPE_EXTEND) advances the output buffer by a fixed amount while the guard tracks name length, allowing an out-of-bounds read/write when name fragments are long/short. The bug arises becau...

USN-8477-3: tar regression

USN-8477-1 fixed a vulnerability in tar. That fix was incomplete and could cause tar to fail to extract old archives that recorded a nonzero size for directory entries, resulting in a regression. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was...

CVE-2026-63817

A flaw was found in the Linux kernel's F2FS file system. When the compresscache mount option is disabled, a corrupted directory entry could point to an invalid inode number. The system incorrectly processes this as a valid internal inode, bypassing critical validation checks. This vulnerability...
