Descriptions
In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently.
En el kernel de Linux versiones anteriores a 5.17.3, el archivo fs/io_uring.c presenta un uso de memoria previamente liberada debido a una condición de carrera en la función io_uring timeouts. Esto puede ser desencadenado por un usuario local que no tenga acceso a ningún espacio de nombres de usuario; sin embargo, la condición de carrera quizás sólo pueda ser explotada con poca frecuencia
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
