{"id":"AZL-77259","summary":"CVE-2026-23084 affecting package kernel for versions less than 6.6.126.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbe2net: Fix NULL pointer dereference in be_cmd_get_mac_from_list\n\nWhen the parameter pmac_id_valid argument of be_cmd_get_mac_from_list() is\nset to false, the driver may request the PMAC_ID from the firmware of the\nnetwork card, and this function will store that PMAC_ID at the provided\naddress pmac_id. This is the contract of this function.\n\nHowever, there is a location within the driver where both\npmac_id_valid == false and pmac_id == NULL are being passed. This could\nresult in dereferencing a NULL pointer.\n\nTo resolve this issue, it is necessary to pass the address of a stub\nvariable to the function.","modified":"2026-08-28T17:47:51.038587037Z","published":"2026-02-04T17:16:19Z","upstream":["CVE-2026-23084"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23084"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-77259.json"}}],"schema_version":"1.9.0"}
