{"apiVersion":"1.0","identifier":"CVE-2026-74559","description":"In the Linux kernel, the following vulnerability has been resolved: xsk: drain continuation descs after overflow in xsk_build_skb() Fix generic xmit path multi-buffer logic when packets are either too big (count of descriptors exceed MAX_SKB_FRAGS) or an invalid descriptor is included in fragmented packet. Introduce xdp_sock::drain_cont and act upon this flag - when it is set, keep on consuming descriptors from AF_XDP Tx ring and put them directly onto Cq. Previously these descriptors were silently lost and could never be reached again.","publishedAt":"2026-08-15T13:18:01","lastModifiedAt":"2026-08-17T06:19:54","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74559","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00166,"riskScore":0,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74559","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74559","en":"https://www.redsauce.net/en/cves/CVE-2026-74559","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74559","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74559","de":"https://www.redsauce.net/de/cves/CVE-2026-74559","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74559","el":"https://www.redsauce.net/el/cves/CVE-2026-74559"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74559"}}
