CVE-2025-22114

5.5 mediumEPSS 0.2%

Medium (5.5) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: btrfs: don't clobber ret in btrfs_validate_super() Commit 2a9bb78cfd36 ("btrfs: validate system chunk array at btrfs_validate_super()") introduces a call to validate_sys_chunk_array() in btrfs_validate_super(), which clobbers the value of ret set earlier. This has the effect of negating the validity checks done earlier, making it so btrfs could potentially try to mount invalid filesystems.
