Answer in brief
CVE-2024-38568 records a Unknown severity vulnerability in drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group The perf tool allows users to create event groups through following cmd [1], but the driver does not check whether the array index is out of bounds when writing data to the event_group array. If the number of events in an event_group is greater than HNS3_PMU_MAX_HW_EVENTS, the memory write overflow of event_group array occurs. Add array index check to fix the possible array out of bounds violation, and return directly when write new events are written to array bounds. There are 9 different events in an event_group. [1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}
