CVE-2024-26598 is fixed in 22 products on 1 platform, first by ALAS2023-2024-519, released February 15, 2024. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2024-26598 - Priority: High - CVSS: 7.8 (high) - EPSS: 0.0024 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Feb 15, 2024 ## Description In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache There is a potential UAF scenario in the case of an LPI translation cache hit racing with an operation that invalidates the cache, such as a DISCARD ITS command. The root of the problem is that vgic_its_check_cache() does not elevate the refcount on the vgic_irq before dropping the lock that serializes refcount changes. Have vgic_its_check_cache() raise the refcount on the returned vgic_irq and add the corresponding decrement after queueing the interrupt. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | bpftool amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | bpftool-debuginfo amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-debuginfo amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-debuginfo-common-aarch64 amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-debuginfo-common-x86_64 amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-devel amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-headers amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-libbpf amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-libbpf-devel amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-libbpf-static amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-livepatch-6.1.75-99.163 amzn 2023 | 1.0-0.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-modules-extra amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-modules-extra-common amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-tools amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-tools-debuginfo amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | kernel-tools-devel amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | linux Debian 12.15 (bookworm) | 6.1.76-1 | [DEBIAN-CVE-2024-26598](https://patchblox.com/security/data/fix/linux/debian-cve-2024-26598.md) | Feb 23, 2024 | | Linux | linux Debian 13.5 (trixie) | 6.6.15-1 | [DEBIAN-CVE-2024-26598](https://patchblox.com/security/data/fix/linux/debian-cve-2024-26598.md) | Feb 23, 2024 | | Linux | linux Debian 14 | 6.6.15-1 | [DEBIAN-CVE-2024-26598](https://patchblox.com/security/data/fix/linux/debian-cve-2024-26598.md) | Feb 23, 2024 | | Linux | perf amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | perf-debuginfo amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | python3-perf amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | | Linux | python3-perf-debuginfo amzn 2023 | 6.1.75-99.163.amzn2023 | [ALAS2023-2024-519](https://patchblox.com/security/data/fix/linux/alas2023-2024-519.md) | Feb 15, 2024 | --- Data as of 2026-11-09T07:25:28Z UTC.
