{"id":"AZL-103592","summary":"CVE-2026-97518 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: reject duplicate wiphy cipher suite entries\n\nDuplicate entries in wiphy-\u003ecipher_suites do not describe any\nadditional capability, but cfg80211 currently accepts them and leaves\nindividual consumers to deal with them.\n\nOne such consumer is the WEXT compatibility code, which appends a WEP\nkey length for each WEP cipher entry it sees. Repeated WEP entries can\ntherefore overflow the fixed iw_range::encoding_size array returned by\nSIOCGIWRANGE.\n\nReject duplicate cipher suite entries in wiphy_register() instead.\nThis keeps the cipher suite invariant in one place and makes malformed\nwiphy descriptions fail early with -EINVAL, rather than relying on a\nsingle cfg80211 user to handle duplicates correctly.","modified":"2026-09-25T14:15:43.051046862Z","published":"2026-09-24T17:17:29Z","upstream":["CVE-2026-97518"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97518"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103592.json"}}],"schema_version":"1.9.0"}
