Linux Kernel Dual-Divider Clock Rate Readback Vulnerability in Sunxi-ng Component

A vulnerability in the Linux kernel's clock management for the Sunxi-ng dual-divider feature has been addressed. The issue arose because the P divider offset was omitted from the rate recalculation function, leading to incorrect clock rates or even a zero value. This problem could potentially cause a divide-by-zero error. The vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability could cause incorrect clock rate calculations, potentially leading to system instability or a divide-by-zero error, which could cause a crash.

Remediation

Users can upgrade to the latest version of the Linux kernel stable tree to address this vulnerability.
