Description
A flaw was found in the Linux kernel's LTC4282 hardware monitoring driver. This vulnerability can lead to a Denial of Service (DoS) due to the use of uninitialized stack memory. The driver fails to initialize its clock data structure during setup, leaving member fields uninitialized. A local attacker capable of triggering device initialization can cause the kernel to access this uninitialized data and crash the system.
