Name of the Vulnerable Software and Affected Versions
Linux Kernel versions prior to v5.15.47
Description
The issue is related to the sysrq feature, which is used to provide a means of retrieving system information and debugging data. The problem arises when showing the backtrace of all active CPUs, where the current CPU is not omitted. This could potentially lead to information disclosure. The actual impact and attack plausibility have not yet been proven.
Recommendations
For Linux Kernel versions prior to v5.15.47, update to version v5.15.47 or later to resolve the issue.
