{"apiVersion":"1.0","identifier":"CVE-2026-74474","description":"In the Linux kernel, the following vulnerability has been resolved: vxlan: use pskb_network_may_pull() for transmit path header pulls In vxlan_xmit(), arp_reduce(), and vxlan_mdb_entry_skb_get(), pskb_may_pull() was being called to verify the availability of network layer headers (ARP, IPv6/ND, IP/IPv6 MDB keys). However, during transmit skb->data points to the MAC header, so skb_network_offset(skb) is ETH_HLEN (14 bytes). Using pskb_may_pull(skb, len) only checks len bytes from skb->data rather than skb_network_offset(skb) + len, which can leave part of the network header in non-linear frags. Replace these remaining pskb_may_pull() calls with pskb_network_may_pull() to properly account for the MAC header offset.","publishedAt":"2026-08-15T13:17:52","lastModifiedAt":"2026-08-23T13:16:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74474","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00457,"riskScore":1.02,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74474","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74474","en":"https://www.redsauce.net/en/cves/CVE-2026-74474","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74474","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74474","de":"https://www.redsauce.net/de/cves/CVE-2026-74474","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74474","el":"https://www.redsauce.net/el/cves/CVE-2026-74474"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74474"}}
