CVE-2025-39954

MEDIUM

Linux Kernel 6.15-6.16.9 - Divide By Zero in Dual-Divider Clock Rate Readback

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: mp: Fix dual-divider clock rate readback When dual-divider clock support was introduced, the P divider offset was left out of the .recalc_rate readback function. This causes the clock rate to become bogus or even zero (possibly due to the P divider being 1, leading to a divide-by-zero). Fix this by incorporating the P divider offset into the calculation.
