CVE-2024-35925: block: prevent division by zero in blk_rq_stat_sum()

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.22% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 21e7d72d0cfcbae6042d498ea2e6f395311767f8, 512a01da7134bac8f8b373506011e8aaa3283854, 5f7fd6aa4c4877d77133ea86c14cf256f390b2fe.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 21e7d72d0cfcbae6042d498ea2e6f395311767f8, 512a01da7134bac8f8b373506011e8aaa3283854, 5f7fd6aa4c4877d77133ea86c14cf256f390b2fe or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: block: prevent division by zero in blk_rq_stat_sum() The expression dst->nr_samples + src->nr_samples may have zero value on overflow. It is necessary to add a check to avoid division by zero. Found by Linux Verification Center (linuxtesting.org) with Svace.
