Hi,
The following vulnerability was published for firmware-nonfree.
CVE-2023-4969[0]:
| A GPU kernel can read sensitive data from another GPU kernel (even
| from another user or app) through an optimized GPU memory region
| called _local memory_ on various architectures.
There are though some unclarities about this, so just filling for
keeping track of the issue. [1] mentions that AMD expects to to start
rolling out mitigations beginning of March 2024, so we might see then
more where the mitigations lies and if firmware-nonfree are correct.
They mention there rather "upcoming driver updates".
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
