CVE-2025-68743 is fixed in 14 products on 1 platform, first by DEBIAN-CVE-2025-68743, released December 24, 2025. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2025-68743 - Priority: Routine - CVSS: n/a - EPSS: 0.0019 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Dec 24, 2025 ## Description In the Linux kernel, the following vulnerability has been resolved: mshv: Fix create memory region overlap check The current check is incorrect; it only checks if the beginning or end of a region is within an existing region. This doesn't account for userspace specifying a region that begins before and ends after an existing region. Change the logic to a range intersection check against gfns and uaddrs for each region. Remove mshv_partition_region_by_uaddr() as it is no longer used. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | dtb-aarch64 opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-64kb opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-64kb sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-azure opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-azure sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-default opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-default sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-default-base opensuse-leap 16.0 | 6.12.0-160000.26.1.160000.2.7 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-default-base sles 16.0 | 6.12.0-160000.26.1.160000.2.7 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-docs opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-docs sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-kvmsmall opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-kvmsmall sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-obs-build opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-obs-qa opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-obs-qa sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-rt opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-source opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-source sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-syms opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-syms sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | kernel-zfcpdump opensuse-leap 16.0 | 6.12.0-160000.26.1 | [OPENSUSE-SU-2026:20287-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-20287-1.md) | Feb 27, 2026 | | Linux | kernel-zfcpdump sles 16.0 | 6.12.0-160000.26.1 | [SUSE-SU-2026:20599-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-20599-1.md) | Feb 27, 2026 | | Linux | linux Debian 14 | 6.17.13-1 | [DEBIAN-CVE-2025-68743](https://patchblox.com/security/data/fix/linux/debian-cve-2025-68743.md) | Dec 24, 2025 | --- Data as of 2026-11-09T13:31:49Z UTC.
