CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.10.9
Description
The issue is related to the serialization of the AUX buffer in the Linux kernel. Specifically, the
event->mmap mutex is insufficient to serialize the AUX buffer, allowing for potential deserialization issues. This could impact the confidentiality, integrity, and availability of the system. The problem arises from the incorrect lock order of perf event::mmap mutex under mmap lock.Recommendations
To resolve the issue, upgrade the Linux kernel to a version newer than 6.10.9. As a temporary workaround, consider restricting access to the vulnerable
perf/aux component until a patch is applied.Exploit
Fix
Memory Corruption
Deserialization of Untrusted Data
