CVE-2024-56595

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

Description A vulnerability in the Linux kernel has been resolved. The issue is related to an array-index-out-of-bounds condition in the dbAdjTree function of the jfs module. When the value of lp is 0 at the beginning of the for loop, it becomes negative in the next assignment, requiring the loop to terminate.

Recommendations For Linux kernel versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue. As a temporary workaround, consider disabling the jfs module until a patch is available. Restrict access to the dbAdjTree function to minimize the risk of exploitation. Avoid using the lp variable in the affected loop until the issue is resolved.
