Subject: Re: [PATCH] x86/mm/pat: acquire mmap lock on page table free to avoid ptdump UAF
Date: Sun, 12 Jul 2026 11:46:30 +0100 [thread overview]
Message-ID: <alNwO-lnRDsWPrB6@lucifer> (raw)
In-Reply-To: <20260710-fix-cpa-ptdump-race-v1-1-d898699a7417@kernel.org>

[0].
In the end agree with Mike that it's just simpler to keep everything together as
one :)
Cheers, Lorenzo
