{"id":"AZL-90983","summary":"CVE-2026-52922 affecting package kernel for versions less than 6.6.143.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: dat: handle forward allocation error\n\nbatadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb\nfor each DHT candidate, but does not check the return value before passing\nit to batadv_send_skb_prepare_unicast_4addr(). That function dereferences\nthe skb unconditionally, so a failed allocation triggers a NULL pointer\ndereference.\n\nSkip forwarding to the current DHT candidate on allocation failure.","modified":"2026-08-28T17:47:39.157567532Z","published":"2026-06-24T08:16:22Z","upstream":["CVE-2026-52922"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52922"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.143.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-90983.json"}}],"schema_version":"1.9.0"}
