Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - clear AES key schedule from stack qat_alg_xts_reverse_key() expands the forward XTS AES key on the stack. That schedule contains key material and can remain in the stack frame. Clear the temporary crypto_aes_ctx with memzero_explicit() after the copy.
