Subject: [PATCH 5.10/5.15/6.1 0/5] x86/mm: backport fixes for CVE-2023-0597 and CVE-2023-3640
Date: Wed, 13 Nov 2024 01:41:56 +0300 [thread overview]
Message-ID: <20241112224201.289285-1-kovalev@altlinux.org> (raw)
This series addresses two security vulnerabilities (CVE-2023-0597 [1],
CVE-2023-3640 [2]) in the x86 memory management subsystem, alongside
prerequisite [3] patches necessary for stable integration.
[PATCH 5.10/5.15/6.1 1/5] x86/kasan: Map shadow for percpu pages on demand
Ensures KASAN shadow mapping on demand for per-CPU pages.
[PATCH 5.10/5.15/6.1 2/5] x86/mm: Recompute physical address for every page of per-CPU CEA mapping
Calculates accurate physical addresses across CPU entry areas.
[PATCH 5.10/5.15/6.1 3/5] x86/mm: Populate KASAN shadow for entire per-CPU range of CPU entry area
Populates KASAN shadow memory for debugging across CPU entry areas.
[PATCH 5.10/5.15/6.1 4/5] x86/mm: Randomize per-cpu entry area
Randomizes the per-CPU entry area to reduce the risk of information leakage
due to predictable memory layouts, especially in systems without KASLR, as
described in CVE-2023-0597 [1].
[PATCH 5.10/5.15/6.1 5/5] x86/mm: Do not shuffle CPU entry areas without KASLR
Prevents CPU entry area shuffling when KASLR is disabled, mitigating information
leakage risks, as stated in CVE-2023-3640 [2].
