Vulnerability from github – Published: 2024-05-17 15:31 – Updated: 2025-12-23 21:30

Details

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.

Severity ?

7.8 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
