CVE-2024-38635 Open this link in a new tabHow to fix?
There is no fixed version for Centos:8 kernel-tools.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-tools package and not the kernel-tools package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
soundwire: cadence: fix invalid PDI offset
For some reason, we add an offset to the PDI, presumably to skip the PDI0 and PDI1 which are reserved for BPT.
This code is however completely wrong and leads to an out-of-bounds access. We were just lucky so far since we used only a couple of PDIs and remained within the PDI array bounds.
A Fixes: tag is not provided since there are no known platforms where the out-of-bounds would be accessed, and the initial code had problems as well.
A follow-up patch completely removes this useless offset.
