  3. CVE-2024-56623
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix use after free on unload System crash is observed with stack trace warning of use after free. There are 2 signals to tell dpc_thread to terminate (UNLOADING flag and kthread_stop). On setting the UNLOADING flag when dpc_thread happens to run at the time and sees the flag, this causes dpc_thread to exit and clean up itself. When kthread_stop is called for final cleanup, this causes use after free. Remove UNLOADING signal to terminate dpc_thread. Use the kthread_stop as the main signal to exit dpc_thread.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: qla2xxx: Se corrige el use-after-free en la descarga Se observa un fallo del sistema con una advertencia de seguimiento de la pila de use-after-free. Hay 2 señales para indicar a dpc_thread que finalice (indicador UNLOADING y kthread_stop). Al establecer el indicador UNLOADING cuando dpc_thread se está ejecutando en ese momento y ve el indicador, esto hace que dpc_thread salga y se limpie a sí mismo. Cuando se llama a kthread_stop para la desinfección final, esto provoca el use-after-free. Eliminar la señal UNLOADING para finalizar dpc_thread. Usar kthread_stop como la señal principal para salir de dpc_thread. [596663.812935] ¡ERROR del kernel en mm/slub.c:294!
