Description OSIDB Bzimport 2026-08-22 15:45:34 UTC 
In the Linux kernel, the following vulnerability has been resolved:

fs,fsverity: remove check for fsverity being enabled in setattr_prepare()

The check that fs-verity is available in the kernel is not necessary
here. Filesystems could have fsverity files even without fs-verity
enabled. In that case, truncate on fsverity file will succeed, what this
check is trying to prevent.
