CVE-2026-89767

A flaw was found in the Linux kernel's overlay file system overlayfs. An unprivileged local user can trigger a specific error condition during the creation of a new directory. This error causes the system to incorrectly release a lock on the parent directory and a reference to the new directory...

CVE-2026-89768

A flaw was found in the Linux kernel's filesystem fs component. When using nested overlay filesystems overlayfs, a local user could exploit an issue where the backingfileopen function incorrectly derives the path for mapped files. This vulnerability leads to information disclosure, as files mappe...

CVE-2026-89560

A flaw was found in the Linux kernel's Landlock security module. This vulnerability allowed for the creation of 'whiteout' objects without proper permission checks. Whiteout objects are special files used in OverlayFS to hide underlying files, and their unauthorized creation could lead to...
