GHSA-VVMC-4GQR-H5J4

Vulnerability from github – Published: 2024-10-21 12:30 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate()

The psc->div[] array has psc->num_div elements. These values come from when we call clk_hw_register_div(). It's adc_divisors and ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >= instead of > to prevent an out of bounds read.

Severity ?

7.1 (High)
