Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to a possible kernel memory corruption due to improper locking in multiple functions of io uring.c. This could lead to local escalation of privilege in the kernel wi...

Linux kernel buffer overflow vulnerability (CNVD-2022-38757)

Linux kernel is the kernel used by the Linux Foundation's open source operating system, Linux. Linux kernel is vulnerable to a buffer overflow vulnerability that stems from a boundary error in iouring when handling untrusted input. A remote attacker could exploit this vulnerability to cause an...

Integer Overflow or Wraparound vulnerability in iouring of Linux Kernel allows local attacker to cause memory corruption and escalate privileges to root. This issue affects: Linux Kernel versions prior to 5.4.189; version 5.4.24 and later versions...

The vulnerability of the fs/io_uring.c file in the io_uring subsystem of the Linux operating system allows a attacker to cause a service failure or gain increased privileges.

The vulnerability of the fs/iouring.c file in the iouring subsystem of the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to cause a service failure or increase their privileges...

In the Linux kernel before 5.17.3 fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however the race condition perhaps can only be exploited infrequently.
