CVE-2023-52859

7.8 · HIGH
Published May 21, 2024 linux CWE-416 EPSS 0.24% (15th pctl)

Overview

CVE-2023-52859 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 21, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

perf: hisi: Fix use-after-free when register pmu fails

When we fail to register the uncore pmu, the pmu context may not been

allocated. The error handing will call cpuhp_state_remove_instance()

to call uncore pmu offline callback, which migrate the pmu context.

Since that's liable to lead to some kind of use-after-free.

Use cpuhp_state_remove_instance_nocalls() instead of

cpuhp_state_remove_instance() so that the notifiers don't execute after

the PMU device has been failed to register.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
