Linux kernel (GCP) vulnerabilities

Beschreibung

Im Linux-Kernel wurde die folgende Schwachstelle behoben: `af_unix`: Setze `gc_in_progress` auf wahr in `unix_gc()`. Igor Ushakov berichtete, dass `unix_gc()` mit `gc_in_progress` als falsch ausgeführt werden könnte, wenn die Arbeit geplant wird, während sie läuft: 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 = false `unix_peek_fpl()` verlässt sich darauf, dass `gc_in_progress` nicht den GC durch MSG_PEEK verwirrt. Lassen Sie uns `gc_in_progress` auf wahr in `unix_gc()` setzen.

    • Affected: Linux, Linux
    • Description: 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 = false unix_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().
