Linux io_uring Heap Buffer Overflow Privilege Escalation
The vulnerability of the ioprepasyncwork function in the iouring subsystem of the Linux operating system is related to the use of previously freed memory. Exploiting this vulnerability can allow an attacker to increase their privileges...
A use-after-free flaw was found in io_uring/filetable.c in io_install_fixed_file in the io_uring subcomponent in the Linux Kernel during call cleanup. This flaw may lead to a denial of service.
...
A use-after-free flaw was found in io_uring/poll.c in io_poll_check_events in the io_uring subcomponent in the Linux Kernel due to a race condition of poll_refs. This flaw may cause a NULL pointer dereference.
