  "description": "In the Linux kernel, the following vulnerability has been resolved:  s390/crypto: Fix skcipher_walk return code handling in aes_s390  The return codes from skcipher_walk_virt() were not properly checked before entering the processing loops in ecb_aes_crypt() and ctr_aes_crypt(). If skcipher_walk_virt() fails, the walk structure may be in an undefined state, and attempting to process data could lead to incorrect behavior or accessing uninitialized memory.  Add proper return code checking to ensure correct handling of the walk initialization and walk advance and eventually return to the caller with that return code.",
