Technical description

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

thermal: intel: powerclamp: fix mismatch in get function for max_idle

KASAN reported this

[ 444.853098] BUG: KASAN: global-out-of-bounds in param_get_int+0x77/0x90

[ 444.853111] Read of size 4 at addr ffffffffc16c9220 by task cat/2105

...

[ 444.853442] The buggy address belongs to the variable:

[ 444.853443] max_idle+0x0/0xffffffffffffcde0 [intel_powerclamp]

There is a mismatch between the param_get_int and the definition of

max_idle. Replacing param_get_int with param_get_byte resolves this

issue.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
