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. The Linux kernel CVE team has assigned CVE-2026-74596 to this issue. Affected and fixed versions =========================== Issue introduced in 7.0 with commit e9734653c523c744f03333ece6ae7a315187f05c and fixed in 7.1.9 with commit 2d2b2ed7bdcc6df4942292318c5455b5e94ba525 Issue introduced in 7.0 with commit e9734653c523c744f03333ece6ae7a315187f05c and fixed in 7.2 with commit d2f96bcb89d36d488a10e3bcf819b98536968286 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-74596 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: fs/attr.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/2d2b2ed7bdcc6df4942292318c5455b5e94ba525 https://git.kernel.org/stable/c/d2f96bcb89d36d488a10e3bcf819b98536968286
