Description OSIDB Bzimport 2025-02-26 03:17:47 UTC 
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.
