CVE-2026-93161

Estado: RecibidaSin puntuar—

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.
