Technical description

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

crypto: s390/aes - Fix buffer overread in CTR mode

When processing the last block, the s390 ctr code will always read

a whole block, even if there isn't a whole block of data left. Fix

this by using the actual length left and copy it into a buffer first

for processing.

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.
