Current rung: Nothing observed in held sources.

- RUNG 4Ransomware campaign use known
A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.
What it is stated by the CNA
Software installed and run as a non-privileged user may conduct improper GPU system calls to subvert GPU HW to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour. This attack can lead the GPU to perform write operations on restricted internal GPU buffers that can lead to a second order affect of corrupted arbitrary physical memory. receipt

The full biography
Exploit probability more than doubled between 2026-06-12 and 2026-06-15 (0.00018 → 0.00132) and the record had been public for 7 months when this index was last written.
The pattern, elsewhere
This record is one instance of CWE-119, improper restriction of operations within the bounds of a memory buffer. The index holds 14297 prior instances of this class, 57 KEV-listed. The nearest of its KEV-listed records are drawn beside this. [email protected]
"Matches n of m" counts the attributes the two records can both be compared on: the CVSS metrics they share a version of, any weakness class beyond this one, and the vendor. fit-rules@v1
14297 records in this class held. The six above are drawn from the ones CISA has listed as exploited, ranked by how much of the record matches this one. That is why every one of them is KEV-listed: the pool is, so the colour on those spokes says nothing the pool has not already said.
No curated product neighbourhood is held for this product, so the records above are the nearest this index can name. The neighbourhood table covers a small set of products and is extended by hand.

Its defect family
imagination technologies graphics ddk
Of the 2 records in this family, this is the only one holding a stated fix version: 25.3 RTM.
Grouped by shared product and weakness, not by shared vulnerability. Each record's own state is on its own page.
Family membership: held values
This record is one of a group, and the group's page describes all of them. This page is kept and dated, and the advisory's own page is the one we offer for indexing: the whole group.
Announced with 37 others
This record was published as one of 38 that cite a single advisory. The batch page names that advisory, counts what the group offers, and says what it does not cover.
Listed for shared announcement, not shared vulnerability. Each record here is its own finding with its own page, and fixing one does not address another.
