Last modified

CVE-2024-49986 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
