CVE-2024-53126

Kernel-memory disclosure and crash via dangling name

Published Dec 4, 2024 · Updated Aug 5, 2026

Use-after-scope in the Linux SolidRun vDPA driver allows local users to disclose kernel memory by reading /proc/iomem. psnet_open_pf_bar() and snet_open_vf_bar() store stack-backed resource names that pcim_iomap_regions() retains after their stack frames disappear. A low-privileged user can trigger the stale read after the SolidNET DPU driver probes, leaking stack data or causing a kernel oops.
