CVE-2024-50251: netfilter: nft_payload: sanitize offset and length before calling skb_checksum()

MediumCVSS 6.2 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.53% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0ab3be58b45b996764aba0187b46de19b3e58a72, a661ed364ae6ae88c2fafa9ddc27df1af2a73701, ac7df3fc80fc82bcc3b1e8f6ebc0d2c435d0c534; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1.

Low priority for now. Upgrade to Linux Linux 0ab3be58b45b996764aba0187b46de19b3e58a72, a661ed364ae6ae88c2fafa9ddc27df1af2a73701, ac7df3fc80fc82bcc3b1e8f6ebc0d2c435d0c534; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_payload: sanitize offset and length before calling skb_checksum() If access to offset + length is larger than the skbuff length, then skb_checksum() triggers BUG_ON(). skb_checksum() internally subtracts the length parameter while iterating over skbuff, BUG_ON(len) at the end of it checks that the expected length to be included in the checksum calculation is fully consumed.
