CVE-2024-53206

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-53206
In the Linux kernel, the following vulnerability has been resolved: tcp: Fix use-after-free of nreq in reqsk_timer_handler(). The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with __inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler(). Then, oreq should be passed to reqsk_put() instead of req; otherwise use-after-free of nreq could happen when reqsk is migrated but the retry attempt failed (e.g. due to timeout). Let's pass oreq to reqsk_put().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tcp: Se corrige el use-after-free de nreq en reqsk_timer_handler(). el commit citada reemplazó inet_csk_reqsk_queue_drop_and_put() con __inet_csk_reqsk_queue_drop() y reqsk_put() en reqsk_timer_handler(). Luego, oreq se debe pasar a reqsk_put() en lugar de req; de lo contrario, el use-after-free de nreq podría ocurrir cuando se migra reqsk pero el intento de reintento falla (por ejemplo, debido al tiempo de espera). Pasemos oreq a reqsk_put().
