Name of the Vulnerable Software and Affected Versions
Android kernel
Description
The issue is related to a double free vulnerability in the
binder alloc free page function of binder alloc.c in the Android kernel. This could lead to a local escalation of privilege in the kernel without needing additional execution privileges. The vulnerability can be exploited without user interaction.Recommendations
For Android kernel, consider applying a patch to fix the improper locking issue in the
binder alloc free page function as a permanent solution. As a temporary workaround, restricting access to the kernel's binder alloc module may help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
