Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw in the lontium-lt9611 driver where a NULL pointer dereference can occur within the lt9611 connector init() function. Specifically, the code dereferences the bridge->encoder pointer without ensuring it is not NULL, potentially leading to a system crash or other undefined behavior. The issue arises from a NULL check that occurs after the pointer has already been dereferenced.
