Consequently, BPF map operations can trigger\nWARN_ON_ONCE(!bpf_rcu_lock_held()) when called from the KCM strparser\nprogram.\n\nHold the RCU read lock while running the program.","modified":"2026-09-18T14:15:19.767421340Z","published":"2026-09-17T17:17:07Z","upstream":["CVE-2026-90143"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90143"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102017.json"}}],"schema_version":"1.9.0"}
