CVE-2024-38568

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to an out-of-bound access in the hns3 pmu validate event group() function in the Linux kernel. This occurs when the perf tool is used to create event groups, and the driver does not check if the array index is out of bounds when writing data to the event group array. If the number of events in an event group exceeds HNS3 PMU MAX HW EVENTS, a memory write overflow of the event group array can happen. The vulnerability can be exploited to impact the confidentiality, integrity, and availability of protected information. The perf stat command with the -e option can be used to create event groups, for example, perf stat -e '{pmu/event1/, ... ,pmu/event9/}'.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
