The vulnerability of the io_ring_buffer_select() function in the io_uring component of the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the ioringbufferselect function in the iouring component of the Linux operating system is related to the dereferencing of a NULL pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

Linux io_uring Use-After-Free Exploit

The Linux kernel suffers from a use-after-free of struct ioevfd because ioeventfddosignal frees an object when the refcount reaches zero without waiting for the required grace period. Summary UAF of struct ioevfd because ioeventfddosignal frees an object when the refcount reaches zero without...
