CVE-2026-68460

A flaw was found in the Linux kernel's f2fs filesystem. When the filesystem space is nearly exhausted, a local attacker could trigger a deadlock within the f2fs_balance_fs() function. This can cause system tasks to become unresponsive, leading to a Denial of Service (DoS) condition.

This vulnerability is evaluated as having a Moderate impact because exploitation requires an authenticated local attacker to trigger near-exhaustion storage capacity, resulting in a denial of service without compromising confidentiality or integrity. Standard Red Hat Enterprise Linux kernels do not enable or ship support for the f2fs file system, preventing exposure on supported configurations.
