Revision f7dc4c9a855a13dbb33294c9fc94f17af03f6291 authored by John Johansen on 08 November 2017, 16:09:52 UTC, committed by Linus Torvalds on 08 November 2017, 18:56:22 UTC
This came in yesterday, and I have verified our regression tests
were missing this and it can cause an oops. Please apply.
There is a an off-by-one comparision on sig against MAXMAPPED_SIG
that can lead to a read outside the sig_map array if sig
is MAXMAPPED_SIG. Fix this.
Verified that the check is an out of bounds case that can cause an oops.
Revised: add comparison fix to second case
Fixes: cd1dbf76b23d ("apparmor: add the ability to mediate signals")
