{"apiVersion":"1.0","identifier":"CVE-2026-80715","description":"In the Linux kernel, the following vulnerability has been resolved: igc: remove napi_synchronize() in igc_down() When an AF_XDP zero-copy application is killed abruptly, the XSK pool is torn down but NAPI keeps polling. igc_clean_rx_irq_zc() then returns the full budget on every poll, so napi_complete_done() never clears NAPI_STATE_SCHED. igc_down() calls napi_synchronize() before napi_disable(), so it spins forever waiting for that bit and the interface never goes down. Drop the napi_synchronize() and let napi_disable() do the job -- it sets NAPI_STATE_DISABLE, which forces the stuck poll to complete. Reorder it ahead of igc_set_queue_napi() so the NAPI mapping is cleared only after polling has stopped, matching the recent igb fix b1e067240379.","publishedAt":"2026-08-28T08:16:57","lastModifiedAt":"2026-08-28T08:16:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80715","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00161,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80715","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80715","en":"https://www.redsauce.net/en/cves/CVE-2026-80715","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80715","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80715","de":"https://www.redsauce.net/de/cves/CVE-2026-80715","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80715","el":"https://www.redsauce.net/el/cves/CVE-2026-80715"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80715"}}
