high Tenable Cloud Security Plugin ID 462064

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: binder: fix UAF in
 binder_free_transaction() In binder_free_transaction(), the t->to_proc is read under the t->lock. However,
 once the t->lock is dropped, the to_proc can die in parallel. This leads to a use-after-free error when we
 attempt to acquire its inner lock right afterwards:

 ================================================================== To prevent this, pin the target thread
 (t->to_thread) to guarantee the target process remains alive. Undelivered transactions without a target
 thread are already safe, as the target process can only be the current context in those paths.
