CVE-2024-38569: drivers/perf: hisi_pcie: 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 3d1face00ebb7996842aee4214d7d0fb0c77b1e9, 567d34626c22b36579ec0abfdf5eda2949044220, 77fce82678ea5fd51442e62febec2004f79e041b.

Low priority for now. Upgrade to Linux Linux 3d1face00ebb7996842aee4214d7d0fb0c77b1e9, 567d34626c22b36579ec0abfdf5eda2949044220, 77fce82678ea5fd51442e62febec2004f79e041b or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi_pcie: 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 HISI_PCIE_MAX_COUNTERS, 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/}'
