CVE-2022-40768

Name of the Vulnerable Software and Affected Versions Linux kernel versions through 5.19.9

Description The issue is related to the stex queuecommand lck() function in the Linux kernel, which is associated with the disclosure of information in an error data area. This can allow an attacker to gain unauthorized access to protected information. The problem arises because stex queuecommand lck lacks a memset for the PASSTHRU CMD case, enabling local users to obtain sensitive information from kernel memory.

Recommendations For Linux kernel versions through 5.19.9, consider updating to a version that includes a fix for this issue, as the current version allows local users to obtain sensitive information due to a missing memset in the stex queuecommand lck function for the PASSTHRU CMD case. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
