Summary
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
