CVE-2024-27038

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: The issue is related to a NULL pointer dereference in the clk core get() function. This function can dereference a NULL pointer in a specific sequence of calls, including of clk get hw from clkspec(), of clk get hw from provider(), and clk get hw(). The clk get hw() function can return NULL, which is then dereferenced by clk core get() at hw->core. Prior to a specific commit, a check was performed that would have caught the NULL pointer. The function needs to be updated to check for hw before dereferencing it and return NULL if hw is NULL.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
