The vulnerability of the Linux operating system’s kernel allows a hacker to enhance their privileges and execute arbitrary code on the target system.

The vulnerability of the joinsessionkeyring function in the Linux operating system’s kernel is related to the use of memory after it is freed. Exploiting this vulnerability can allow a local attacker to increase their privileges and execute arbitrary code on the target system...

kernel: Possible use-after-free vulnerability in keyring facility

A use-after-free flaw was found in the way the Linux kernel's key management subsystem handled keyring object reference counting in certain error path of the joinsessionkeyring function. A local, unprivileged user could use this flaw to escalate their privileges on the system...
