Linux Kernel NULL Pointer Dereference Vulnerability in Crypto Driver

Vulnerability

A vulnerability in the Linux kernel's crypto driver for the OcteonTX2 platform has been addressed. The issue was a NULL pointer dereference that occurred in the driver release process when the CONFIG_DM_CRYPT option was enabled. The vulnerability arose because the driver improperly handled the dm-crypt feature, leading to a crash. The driver has been updated to remove the unnecessary CONFIG_DM_CRYPT check, which resolves the NULL pointer dereference issue.

Impact

Exploitation of this vulnerability leads to a kernel NULL pointer dereference, causing a system crash.
