{"apiVersion":"1.0","identifier":"CVE-2026-80681","description":"In the Linux kernel, the following vulnerability has been resolved: vxlan: re-fetch eth header after route_shortcircuit() Before route_shortcircuit(), the eth header pointer is cached from eth_hdr(skb). Inside route_shortcircuit(), pskb_may_pull() can be called, which may reallocate skb->head. In this case, returning to vxlan_xmit() leaves the cached eth pointer pointing to freed memory, leading to a use-after-free when dereferencing eth->h_dest. Fix this by updating eth = eth_hdr(skb) after calling route_shortcircuit().","publishedAt":"2026-08-28T08:16:53","lastModifiedAt":"2026-08-28T08:16:53","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80681","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00176,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80681","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80681","en":"https://www.redsauce.net/en/cves/CVE-2026-80681","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80681","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80681","de":"https://www.redsauce.net/de/cves/CVE-2026-80681","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80681","el":"https://www.redsauce.net/el/cves/CVE-2026-80681"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80681"}}
