—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 2d2b2ed7bdcc6df4942292318c5455b5e94ba525, 3f3b0898557a93122a7f941e6a89adef2bb29ce4, b4c0c41b952c21baed3f822eab508ebbd1d355d9.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2d2b2ed7bdcc6df4942292318c5455b5e94ba525, 3f3b0898557a93122a7f941e6a89adef2bb29ce4, b4c0c41b952c21baed3f822eab508ebbd1d355d9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
