CVE-2024-42236 Open this link in a new tabHow to fix?
Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.22.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: configfs: Prevent OOB read/write in usb_string_copy()
Userspace provided string 's' could trivially have the length zero. Left
unchecked this will firstly result in an OOB read in the form
if (str[0 - 1] == '\n') followed closely by an OOB write in the form str[0 - 1] = '\0'`.
There is already a validating check to catch strings that are too long. Let's supply an additional check for invalid strings that are too short.
