The vulnerability of the io_uring component in the Linux operating system’s kernel, which allows a hacker to increase their privileges through the io_msg_ring() function.
The vulnerability of the iouring component in the Linux operating system’s kernel is related to the improper handling of counters in the function within the iouring/msgring.c module. This leads to the reallocation of previously freed memory. Exploiting this vulnerability can allow an attacker to...
The vulnerability of the __io_sync Cancel() function in the io_uring/cancel.c module of the io_uring component of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information, or to enhance their privileges.
The vulnerability of the iosync Cancel function in the iouring/cancel.c module of the Linux kernel’s iouring component is related to an incorrect definition of the buffer boundary. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibilit...
The vulnerability of the io_uring subsystem in the Linux operating system allows a hacker to increase their privileges.
The vulnerability of the iouring subsystem in the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges...
