In the Linux kernel, the following vulnerability has been resolved: net:
tls: handle backlogging of crypto requests Since we’re setting the
CRYPTO_TFM_REQ_MAY_BACKLOG flag on our requests to the crypto API,
crypto_aead_{encrypt,decrypt} can return -EBUSY instead of -EINPROGRESS in
valid situations. For example, when the cryptd queue for AESNI is full
(easy to trigger with an artificially low cryptd.cryptd_max_cpu_qlen),
requests will be enqueued to the backlog but still processed. In that case,
the async callback will also be called twice: first with err ==
-EINPROGRESS, which it seems we can just ignore, then with err == 0.
Compared to Sabrina’s original patch this version uses the new
tls_*crypt_async_wait() helpers and converts the EBUSY to EINPROGRESS to
avoid having to modify all the error handling paths. The handling is
identical.
