Sources and claim methodology

Upstream source description

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.
