CVE-2024-49986

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

Published Oct 21, 2024 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
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.
