CVE-2026-23299

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-23299
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: purge error queues in socket destructors When TX timestamping is enabled via SO_TIMESTAMPING, SKBs may be queued into sk_error_queue and will stay there until consumed. If userspace never gets to read the timestamps, or if the controller is removed unexpectedly, these SKBs will leak. Fix by adding skb_queue_purge() calls for sk_error_queue in affected bluetooth destructors. RFCOMM does not currently use sk_error_queue.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: Bluetooth: purgar colas de error en destructores de sockets Cuando la marca de tiempo TX está habilitada a través de SO_TIMESTAMPING, los SKB pueden ser encolados en sk_error_queue y permanecerán allí hasta ser consumidos. Si el espacio de usuario nunca llega a leer las marcas de tiempo, o si el controlador es eliminado inesperadamente, estos SKB se filtrarán. Solución añadiendo llamadas a skb_queue_purge() para sk_error_queue en los destructores de bluetooth afectados. RFCOMM no utiliza actualmente sk_error_queue.
