CVE-2026-89835
A flaw was found in the Linux kernel's f2fs filesystem. This vulnerability occurs when the checkpointmerge feature is enabled without an active checkpoint merge thread, such as during a read-only mount. A local attacker with write access to ckptthreadioprio through sysfs could trigger a null...
