In the Linux kernel, the following vulnerability has been resolved: btrfs: don't clobber ret in btrfsvalidatesuper Commit 2a9bb78cfd36 "btrfs: validate system chunk array at btrfsvalidatesuper" introduces a call to validatesyschunkarray in btrfsvalidatesuper, which clobbers the value of ret set...

CVE-2025-22114

CVE-2025-22114 affects the Linux kernel’s BTRFS subsystem. The root cause is a change in btrfs_validate_super() where a call to validate_sys_chunk_array() clobbers a previously set return value, negating earlier validity checks and potentially allowing mounting of invalid filesystems. The issue h...
