{"id":"AZL-102966","summary":"CVE-2026-92520 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Zero queue and stack outputs on lock failure\n\nQueue and stack pop/peek helpers accept an uninitialized output buffer\nbecause the verifier expects the helper to initialize it. The empty-map\nerror path clears the buffer, but a failed lock acquisition returns\n-EBUSY without writing it.\n\nClear the output before returning -EBUSY so BPF programs cannot observe\nuninitialized stack contents after a failed helper call.","modified":"2026-09-18T14:18:03.058065049Z","published":"2026-09-17T17:17:54Z","upstream":["CVE-2026-92520"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92520"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102966.json"}}],"schema_version":"1.9.0"}
