  3. CVE-2025-21901
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Add sanity checks on rdev validity There is a possibility that ulp_irq_stop and ulp_irq_start callbacks will be called when the device is in detached state. This can cause a crash due to NULL pointer dereference as the rdev is already freed.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/bnxt_re: Se han añadido comprobaciones de seguridad sobre la validez de rdev. Existe la posibilidad de que se invoquen las devoluciones de llamada ulp_irq_stop y ulp_irq_start cuando el dispositivo esté en estado desconectado. Esto puede provocar un bloqueo debido a la desreferencia de punteros nulos, ya que rdev ya está liberado.
