CVE-2022-49260

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

crypto: hisilicon/sec - fix the aead software fallback for engine

Due to the subreq pointer misuse the private context memory. The aead soft crypto occasionally casues the OS panic as setting the 64K page. Here is fix it.

This vulnerability does not affect supported Red Hat Enterprise Linux releases as the problematic implementation in the HiSilicon SEC accelerator driver is not present in Red Hat kernels. The issue is restricted to systems equipped with specific HiSilicon hardware accelerators operating under 64KB page size configurations, which could lead to an operating system crash during AEAD software fallback operations. Therefore, Red Hat enterprise installations do not experience operational risk from this flaw.
