This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

um: work around sched_yield not yielding in time-travel mode

sched_yield by a userspace may not actually cause scheduling in

time-travel mode as no time has passed. In the case seen it appears to

be a badly implemented userspace spinlock in ASAN. Unfortunately, with

time-travel it causes an extreme slowdown or even deadlock depending on

the kernel configuration (CONFIG_UML_MAX_USERSPACE_ITERATIONS).

Work around it by accounting time to the process whenever it executes a

sched_yield syscall.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
