CVE-2024-56690 – Linux Kernel PCrypt Cryptographic Manipulation Vulnerability

CVE ID : CVE-2024-56690

Published : Dec. 28, 2024, 10:15 a.m. | 2 hours, 8 minutes ago

Description : In the Linux kernel, the following vulnerability has been resolved:

crypto: pcrypt – Call crypto layer directly when padata_do_parallel() return -EBUSY

Since commit 8f4f68e788c3 (“crypto: pcrypt – Fix hungtask for
PADATA_RESET”), the pcrypt encryption and decryption operations return
-EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is
generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns
-EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.
Fix this issue by calling crypto layer directly without parallelization
in that case.

Severity: 0.0 | NA
