Description Sam Fowler 2018-08-14 01:29:39 UTC

The Linux kernel is vulnerable to a use-after-free in drivers/android/binder.c. An attacker with local access could potentially exploit this to execute code.

This flaw requires building with CONFIG_ANDROID_BINDER_IPC, which Red Hat and Fedora do not build.
