{"apiVersion":"1.0","identifier":"CVE-2026-74724","description":"In the Linux kernel, the following vulnerability has been resolved: ipvs: avoid out-of-bounds write in ip_vs_nat_icmp Sashiko warns that local attacker can modify the packet while it is processed by IPVS. Some places read the IP ihl field multiple times which can cause out-of-bounds access. One such place is ip_vs_nat_icmp where we can write after the validated area. Fix it by providing ciph argument just like it is done for IPv6 and use ciph->len as offset to the embedded transport header. Modify some IPv4 header checks by reading the ihl field only once.","publishedAt":"2026-08-22T16:16:47","lastModifiedAt":"2026-08-25T06:18:58","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74724","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00123,"riskScore":0.79,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74724","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74724","en":"https://www.redsauce.net/en/cves/CVE-2026-74724","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74724","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74724","de":"https://www.redsauce.net/de/cves/CVE-2026-74724","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74724","el":"https://www.redsauce.net/el/cves/CVE-2026-74724"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74724"}}
