Overview
What is CVE-2026-97590?
In the Linux kernel, the following vulnerability has been resolved:
s390/crypto: Fix missing scrub of temp buffers with PAES algorithm
In function ctr_paes_do_crypt() there is a buffer used to process remaining bytes < AES_BLOCK_SIZE. This buffer was not scrubbed and thus could lead to expose of unwanted data.
Rework the code to explicitly scrub the buffer at the end of the function to avoid exposure of maybe sensitive data.
In function __xts_2keys_prep_param() change the existing scrub to clean the whole param block instead of just the key field.
