What is CVE-2022-22514?

CVE-2022-22514 is a high-severity memory corruption vulnerability in Codesys Control for Beaglebone Sl, published on 7 Apr 2022. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

An authenticated, remote attacker can gain access to a dereferenced pointer contained in a request. The accesses can subsequently lead to local overwriting of memory in the CmpTraceMgr, whereby the attacker can neither gain the values read internally nor control the values to be written. If invalid memory is accessed, this results in a crash.
