Description

An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type. A flaw was discovered in the cryptographic receive code in the Linux kernel's implementation of transparent interprocess communication. An attacker, with the ability to send TIPC messages to the target, can corrupt memory and escalate privileges on the target system.
