CVE-2024-38568: drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 3669baf308308385a2ab391324abdde5682af5aa, 81bdd60a3d1d3b05e6cc6674845afb1694dd3a0e, aa2d3d678895c8eedd003f1473f87d3f06fe6ec7.

Low priority for now. Upgrade to Linux Linux 3669baf308308385a2ab391324abdde5682af5aa, 81bdd60a3d1d3b05e6cc6674845afb1694dd3a0e, aa2d3d678895c8eedd003f1473f87d3f06fe6ec7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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/}
