Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the
audit inode child() function that can lead to a soft lockup. This issue is potentially triggered when using tracefs or debugfs, which may generate a large number of PATH records. An excessive number of these records can cause the system to hang, potentially resulting in a kernel panic. The issue occurs when the system is under specific conditions, such as when CONFIG KASAN=y and CONFIG PREEMPTION=n are enabled, and when audit rules are configured to monitor system calls like open. The problem is addressed by adding cond resched() to the audit inode child() function.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
