Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend (CVE-2022-33741, CVE-2022-33742). ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | bpftool amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | bpftool-debuginfo amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-debuginfo amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-debuginfo-common-aarch64 amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-debuginfo-common-x86_64 amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-devel amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-headers amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-libbpf amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-libbpf-devel amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-libbpf-static amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-livepatch-6.1.10-15.42 amzn 2023 | 1.0-0.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-tools amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-tools-debuginfo amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | kernel-tools-devel amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | linux Debian 12.15 (bookworm) | 5.18.14-1 | [DEBIAN-CVE-2022-33741](https://patchblox.com/security/data/fix/linux/debian-cve-2022-33741.md) | Jul 5, 2022 | | Linux | linux Debian 13.5 (trixie) | 5.18.14-1 | [DEBIAN-CVE-2022-33741](https://patchblox.com/security/data/fix/linux/debian-cve-2022-33741.md) | Jul 5, 2022 | | Linux | linux Debian 14 | 5.18.14-1 | [DEBIAN-CVE-2022-33741](https://patchblox.com/security/data/fix/linux/debian-cve-2022-33741.md) | Jul 5, 2022 | | Linux | perf amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | perf-debuginfo amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | python3-perf amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | python3-perf-debuginfo amzn 2023 | 6.1.10-15.42.amzn2023 | [ALAS2023-2023-070](https://patchblox.com/security/data/fix/linux/alas2023-2023-070.md) | Feb 17, 2023 | | Linux | xen Debian 12.15 (bookworm) | 4.16.2-1 | [DEBIAN-CVE-2022-33741](https://patchblox.com/security/data/fix/linux/debian-cve-2022-33741.md) | Jul 5, 2022 | | Linux | xen Debian 13.5 (trixie) | 4.16.2-1 | [DEBIAN-CVE-2022-33741](https://patchblox.com/security/data/fix/linux/debian-cve-2022-33741.md) | Jul 5, 2022 | | Linux | xen Debian 14 | 4.16.2-1 | [DEBIAN-CVE-2022-33741](https://patchblox.com/security/data/fix/linux/debian-cve-2022-33741.md) | Jul 5, 2022 | --- Data as of 2026-11-08T00:53:09Z UTC.
