Description OSIDB Bzimport 2025-04-16 15:02:02 UTC
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.
