Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2025-39814 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0013 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Sep 16, 2025 ## Description In the Linux kernel, the following vulnerability has been resolved: ice: fix NULL pointer dereference in ice_unplug_aux_dev() on reset Issuing a reset when the driver is loaded without RDMA support, will results in a crash as it attempts to remove RDMA's non-existent auxbus device: echo 1 > /sys/class/net//device/reset BUG: kernel NULL pointer dereference, address: 0000000000000008 ... RIP: 0010:ice_unplug_aux_dev+0x29/0x70 [ice] ... Call Trace: ice_prepare_for_reset+0x77/0x260 [ice] pci_dev_save_and_disable+0x2c/0x70 pci_reset_function+0x88/0x130 reset_store+0x5a/0xa0 kernfs_fop_write_iter+0x15e/0x210 vfs_write+0x273/0x520 ksys_write+0x6b/0xe0 do_syscall_64+0x79/0x3b0 entry_SYSCALL_64_after_hwframe+0x76/0x7e ice_unplug_aux_dev() checks pf->cdev_info->adev for NULL pointer, but pf->cdev_info will also be NULL, leading to the deref in the trace above. Introduce a flag to be set when the creation of the auxbus device is successful, to avoid multiple NULL pointer checks in ice_unplug_aux_dev(). ## 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 | 6.16.5-1 | [DEBIAN-CVE-2025-39814](https://patchblox.com/security/data/fix/linux/debian-cve-2025-39814.md) | Sep 16, 2025 | --- Data as of 2026-11-09T01:18:40Z UTC.
