      "value": "An issue was discovered in the Linux kernel 5.10.x before 5.10.155. A use-after-free in io_sqpoll_wait_sq in fs/io_uring.c allows an attacker to crash the kernel, resulting in denial of service. finish_wait can be skipped. An attack can occur in some situations by forking a process and then quickly terminating it. NOTE: later kernel versions, such as the 5.15 longterm series, substantially changed the implementation of io_sqpoll_wait_sq."

Un use after free en io_sqpoll_wait_sq en fs/io_uring.c permite a un atacante bloquear el kernel, lo que resulta en denegaci\u00f3n de servicio. Finish_wait se puede omitir. En algunas situaciones puede ocurrir un ataque al bifurcar un proceso y luego finalizarlo r\u00e1pidamente. NOTA: las versiones posteriores del kernel, como la serie a largo plazo 5.15, cambiaron sustancialmente la implementaci\u00f3n de io_sqpoll_wait_sq."
