CVE-2021-47354

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

drm/sched: Avoid data corruptions

Wait for all dependencies of a job to complete before killing it to avoid data corruptions.

A flaw in the Linux kernel's DRM GPU scheduler (drm/sched): a job could be killed before all of its dependencies completed, allowing in-flight GPU operations to run against torn-down state and corrupt data. Triggering requires local access to submit GPU scheduler jobs, so Red Hat rates this Moderate (6.0), well below external scores (CVE.org 7.1; CISA 9.1, whose AV:N network vector is incorrect for a local-only GPU bug). Supported Red Hat Enterprise Linux streams are not affected; the RHEL 6 and RHEL 7 ELS kernels predate the DRM GPU scheduler framework, so the vulnerable code is not present.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
