CVE-2025-40161 is fixed in 13 products on 1 platform, first by DEBIAN-CVE-2025-40161, released November 12, 2025. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2025-40161 - Priority: Routine - CVSS: n/a - EPSS: 0.0020 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Nov 12, 2025 ## Description In the Linux kernel, the following vulnerability has been resolved: mailbox: zynqmp-ipi: Fix SGI cleanup on unbind The driver incorrectly determines SGI vs SPI interrupts by checking IRQ number < 16, which fails with dynamic IRQ allocation. During unbind, this causes improper SGI cleanup leading to kernel crash. Add explicit irq_type field to pdata for reliable identification of SGI interrupts (type-2) and only clean up SGI resources when appropriate. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | dtb-aarch64 opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-64kb opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-64kb sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-default opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-default sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-default-base opensuse-leap 16.0 | 6.12.0-160000.8.1.160000.2.5 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-default-base sles 16.0 | 6.12.0-160000.8.1.160000.2.5 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-docs opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-docs sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-kvmsmall opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-kvmsmall sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-obs-build opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-obs-qa opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-obs-qa sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-rt opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-source opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-source sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-syms opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-syms sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | kernel-zfcpdump opensuse-leap 16.0 | 6.12.0-160000.8.1 | [OPENSUSE-SU-2025:20172-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2025-20172-1.md) | Dec 19, 2025 | | Linux | kernel-zfcpdump sles 16.0 | 6.12.0-160000.8.1 | [SUSE-SU-2026:20015-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20015-1.md) | Dec 19, 2025 | | Linux | linux Debian 13.5 (trixie) | 6.12.57-1 | [DEBIAN-CVE-2025-40161](https://patchblox.com/security/data/fix/linux/debian-cve-2025-40161.md) | Nov 12, 2025 | | Linux | linux Debian 14 | 6.17.6-1 | [DEBIAN-CVE-2025-40161](https://patchblox.com/security/data/fix/linux/debian-cve-2025-40161.md) | Nov 12, 2025 | --- Data as of 2026-11-10T01:44:33Z UTC.
