CVE-2022-49262

In the Linux kernel, the following vulnerability has been resolved: crypto: octeontx2 - remove CONFIG_DM_CRYPT check No issues were found while using the driver with dm-crypt enabled. So CONFIG_DM_CRYPT check in the driver can be removed. This also fixes the NULL pointer dereference in driver release if CONFIG_DM_CRYPT is enabled. ... Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 ...
