CVE-2024-49986 Information

Description

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.
