RCU readers walking\nthe same list can still hold a pointer to the object after it has been\nremoved, leading to a slab-use-after-free.\n\nUse kfree_rcu(), matching the lifetime rule already used by\nphonet_address_del() for the same object type.","modified":"2026-08-28T17:48:11.534599385Z","published":"2026-06-25T09:16:33Z","upstream":["CVE-2026-53157"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53157"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.144.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-90455.json"}}],"schema_version":"1.9.0"}
