CVE-2023-53122

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to the fixed version

Description The issue is related to the RISC-V architecture in the Linux kernel, where a mutex lock is taken twice during SiFive errata patching, resulting in errors such as kernel NULL pointer dereferences. This can cause the system to crash, as seen in the provided error log. The estimated number of potentially affected devices is not specified.

Recommendations For Linux kernel versions prior to the fixed version, consider applying the patch that fixes the issue with taking the text mutex twice during sifive errata patching. As a temporary workaround, it may be possible to avoid the crash by ensuring that the mutex lock is not taken twice, although this would require a custom fix. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
