Descriptions

A memory leak flaw was found in the Linux kernel’s io_uring functionality in how a user registers a buffer ring with IORING_REGISTER_PBUF_RING, mmap() it, and then frees it. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Se encontró un fallo de pérdida de memoria en la funcionalidad io_uring del kernel de Linux en cómo un usuario registra un anillo de búfer con IORING_REGISTER_PBUF_RING, mmap() y luego lo libera. este fallo permite que un usuario local falle o potencialmente aumente sus privilegios en el sistema.
