Noroxi assessment
Priority: Monitor (action score 33/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 8.8% (FIRST EPSS); higher than 95.2% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: linux (Debian:10) 4.19.260-1; linux-5.10 (Debian:10) 5.10.136-1~deb10u1; linux (Debian:11) 5.10.136-1.
- Mentioned 3 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to linux (Debian:10) 4.19.260-1; linux-5.10 (Debian:10) 5.10.136-1~deb10u1; linux (Debian:11) 5.10.136-1 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
nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.
