- Details
-
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Set gc_in_progress to true in unix_gc().
Igor Ushakov reported that unix_gc() could run with gc_in_progress being false if the work is scheduled while running:
Thread 1 Thread 2 Thread 3
unix_schedule_gc() unix_schedule_gc() `- if (!gc_in_progress) `- if (!gc_in_progress) |- gc_in_progress = true | `- queue_work() |unix_gc() <----------------/ | | |- gc_in_progress = true ...
- queue_work() | |- gc_in_progress = false | | unix_gc() <---------------------------------------------' | ... /* gc_in_progress == false */ | `- gc_in_progress = falseunix_peek_fpl() relies on gc_in_progress not to confuse GC by MSG_PEEK.
Let's set gc_in_progress to true in unix_gc().
