DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

forcedeth: fix UAF of txrx_stats in nv_remove

nv_remove() frees the per-CPU txrx_stats before unregister_netdev(). Until unregister completes, ndo_get_stats64, the NAPI/xmit data path, and nv_close()/drain may still access txrx_stats, leading to a use-after-free.

Free the stats only after unregister_netdev().

AnalysisAI

Use-after-free in the Linux kernel's forcedeth Ethernet driver allows a local user to trigger kernel memory corruption during device removal. The driver's nv_remove() function frees per-CPU txrx_stats before unregister_netdev() completes, leaving the ndo_get_stats64 statistics path, NAPI polling, xmit data path, and nv_close()/drain all capable of accessing the already-freed structure. …

Vulnerability AssessmentAI

Exploitation Exploitation requires local system access with at least standard user privileges (CVSS PR:L, AV:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a locally exploitable kernel UAF with full confidentiality, integrity, and availability impact - consistent with the well-established exploitation class of kernel memory corruption primitives that can be chained into local privilege escalation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local user on a system with NVIDIA nForce-era Ethernet hardware initiates or waits for a device removal event - such as a hotplug removal, module unload, or system shutdown - while network traffic is actively being processed by the forcedeth driver. The race between nv_remove() freeing txrx_stats and an in-flight ndo_get_stats64() call or NAPI softirq accessing the freed structure creates a use-after-free condition in kernel memory. …
Remediation The primary fix is to upgrade the Linux kernel to a patched stable release: 6.6.151, 6.12.103, 6.18.44, 7.1.8, or 7.2-rc6, depending on the distribution's supported branch. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all systems running forcedeth Ethernet drivers (prevalent on legacy NVIDIA nForce systems) and confirm patch availability from your Linux vendor. …
