CVE-2026-43360

A flaw was found in the Linux kernel's Btrfs file system. A malicious user can exploit this vulnerability by creating multiple files with names that result in the same hash. This action can trigger a transaction abort, causing the file system to switch into a read-only mode. This ultimately leads to a denial of service (DoS), disrupting system operations without requiring administrative privileges.

This Moderate impact flaw in the Linux kernel's Btrfs filesystem allows a local, unprivileged attacker to trigger a transaction abort by creating files with hash collisions. This can lead to a denial of service by forcing the filesystem into a read-only state, disrupting system operations on affected Red Hat Enterprise Linux 10 and Red Hat In-Vehicle OS systems.
