CVE-2024-49986

Kernel compromise via freed pdevs array access

Published Oct 21, 2024 · Updated Aug 5, 2026

Use-after-free in affected Linux kernel 5.17 and later branches allows local users to read or alter kernel data or interrupt the host. The x86_android_tablet_probe function calls x86_android_tablet_remove, which frees the pdevs array, and then reads PTR_ERR from the freed array when platform-device registration fails. Reachability requires the x86-android-tablets driver and a registration error; published records do not explain how a local user can induce that error.
