How to fix?

Upgrade SLES:15.6 kernel-docs to version 6.4.0-150600.23.30.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs package and not the kernel-docs 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:

platform/x86: x86-android-tablets: Fix use after free on platform_device_register() errors

x86_android_tablet_remove() frees the pdevs[] array, so it should not be used after calling x86_android_tablet_remove().

When platform_device_register() fails, store the pdevs[x] PTR_ERR() value into the local ret variable before calling x86_android_tablet_remove() to avoid using pdevs[] after it has been freed.
