{"id":"CVE-2026-23299","summary":"Bluetooth: purge error queues in socket destructors","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: purge error queues in socket destructors\n\nWhen TX timestamping is enabled via SO_TIMESTAMPING, SKBs may be queued\ninto sk_error_queue and will stay there until consumed. If userspace never\ngets to read the timestamps, or if the controller is removed unexpectedly,\nthese SKBs will leak.\n\nFix by adding skb_queue_purge() calls for sk_error_queue in affected\nbluetooth destructors. RFCOMM does not currently use sk_error_queue.","modified":"2026-04-02T13:12:20.837866Z","published":"2026-03-25T10:26:55.481Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23299.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/21e4271e65094172aadd5beb8caea95dd0fbf6d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b6c942a526635f5c61d2f000258e620da32d3a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3de7c10a950b36affc692d8bd2ac713852580e56"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23299.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23299"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"134f4b39df7b77225a80ef585c15d46f964f5e6f"},{"fixed":"2b6c942a526635f5c61d2f000258e620da32d3a7"},{"fixed":"3de7c10a950b36affc692d8bd2ac713852580e56"},{"fixed":"21e4271e65094172aadd5beb8caea95dd0fbf6d7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23299.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.18.17"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23299.json"}}],"schema_version":"1.7.5"}
