{"id":"AZL-82013","summary":"CVE-2026-23403 affecting package kernel for versions less than 6.6.130.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\napparmor: fix memory leak in verify_header\n\nThe function sets `*ns = NULL` on every call, leaking the namespace\nstring allocated in previous iterations when multiple profiles are\nunpacked. This also breaks namespace consistency checking since *ns\nis always NULL when the comparison is made.\n\nRemove the incorrect assignment.\nThe caller (aa_unpack) initializes *ns to NULL once before the loop,\nwhich is sufficient.","modified":"2026-08-28T17:47:55.500841683Z","published":"2026-04-01T09:16:15Z","upstream":["CVE-2026-23403"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23403"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.130.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-82013.json"}}],"schema_version":"1.9.0"}
