The vulnerability of the io_register_pbuf_ring() function in the io_uring/kbuf.c module, a synchronous input/output interface for the Linux kernel, allows a attacker to cause a service failure.

The vulnerability of the ioregisterpbufring function in the iouring/kbuf.c module, a component of the Linux kernel’s asynchronous input/output interface, relates to the distribution of resources without any restrictions or regulation. Exploiting this vulnerability could allow an attacker to cause...
