Vulnerability from github – Published: 2025-09-22 21:30 – Updated: 2025-09-22 21:30In 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.
