A fix is available — apply it.

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

drm/imagination: fix error checking of pvr_vm_context_lookup()

Since pvr_vm_context_lookup() returns either NULL or a pointer, then stop using IS_ERR() for checking the return value.

Using IS_ERR() leads to the kernel oops reported below. It can be reproduced by passing an invalid VM context handle from userspace to the DRM_IOCTL_PVR_CREATE_CONTEXT ioctl.

Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer.

Data Freshness Timeline

(refreshed 8× in last 7d / 36× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 1 repeat row among the latest 86 is merged into the row it repeats.
