CVE-2025-71125

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.18.0-ftest-11964-ge022764176fc-dirty #323
Description The Linux kernel contained an issue where unsupported perf events could be registered with synthetic events. This resulted in a warning message and a potential error when attempting to use perf with synthetic events, such as 'perf record -e synthetic:futex wait'. Specifically, calling tracepoint register functions with a NULL function pointer triggered the issue. The fix involves returning -ENODEV, which prevents the warning and causes perf to error out gracefully.
Recommendations Update to Linux kernel version 6.18.0-ftest-11964-ge022764176fc-dirty #323 or a later version to resolve this issue.
