{"id":"AZL-89048","summary":"CVE-2026-46212 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: bla: prevent use-after-free when deleting claims\n\nWhen batadv_bla_del_backbone_claims() removes all claims for a backbone, it\ndoes this by dropping the link entry in the hash list. This list entry\nitself was one of the references which need to be dropped at the same time\nvia batadv_claim_put().\n\nBut the batadv_claim_put() must not be done before the last access to the\nclaim object in this function. Otherwise the claim might be freed already\nby the batadv_claim_release() function before the list entry was dropped.","modified":"2026-08-28T17:47:53.015701973Z","published":"2026-05-28T10:16:36Z","upstream":["CVE-2026-46212"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46212"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-89048.json"}}],"schema_version":"1.9.0"}
