{"apiVersion":"1.0","identifier":"CVE-2026-80657","description":"In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Guard management mailbox channel cleanup against NULL pointer The management mailbox channel cleanup helpers can be called from error handling paths when mgmt_chann has already been destroyed. Add NULL checks to xdna_mailbox_free_channel() and xdna_mailbox_stop_channel() so the cleanup path safely returns instead of dereferencing a NULL mailbox channel pointer.","publishedAt":"2026-08-28T08:16:50","lastModifiedAt":"2026-08-28T08:16:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80657","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00155,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80657","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80657","en":"https://www.redsauce.net/en/cves/CVE-2026-80657","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80657","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80657","de":"https://www.redsauce.net/de/cves/CVE-2026-80657","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80657","el":"https://www.redsauce.net/el/cves/CVE-2026-80657"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80657"}}
