CVE-2025-40127

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

Description A flaw exists in the Linux kernel related to the hardware random number generator (hwrng) and the ks-sa driver. A division by zero error occurs in the ks sa rng init function due to an uninitialized clock pointer. Specifically, the clk get rate() function is called on an uninitialized pointer, leading to a division by zero when calculating delay values. The issue is resolved by adding clock initialization code before using the clock.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
