CVE-2024-47408

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.74

Description: The issue arises when receiving a proposal message in the server, where the smcd v2 ext offset field from the remote client cannot be fully trusted. If the value of smcd v2 ext offset exceeds the maximum value, it may lead to accessing the wrong address, potentially causing a crash. This is resolved by checking the value of smcd v2 ext offset before using it.

Recommendations: For versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue. As a temporary workaround, consider restricting access to the net/smc module until a patch is available.
