Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY<br /> <br /> Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for<br /> PADATA_RESET"), the pcrypt encryption and decryption operations return<br /> -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is<br /> generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns<br /> -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.<br /> Fix this issue by calling crypto layer directly without parallelization<br /> in that case.
