CVE-2024-42284 is a buffer-overflow vulnerability in the Linux kernel Transparent Inter-Process Communication (TIPC) subsystem. The TIPC UDP address-conversion routine can return success when supplied an invalid UDP media address. The caller subsequently processes the address as valid in the TIPC media-address formatting path, resulting in a buffer-overflow access. The fix makes the conversion routine return a nonzero error status for invalid UDP media addresses.
