CVE-2026-72406 (GCVE-0-2026-72406)

Vulnerability from cvelistv5 – Published: 2026-08-15 05:56 – Updated: 2026-10-16 18:55

Title

net: sungem: fix probe error cleanup

Summary

In the Linux kernel, the following vulnerability has been resolved: net: sungem: fix probe error cleanup gem_init_one() calls gem_remove_one() when register_netdev() fails. gem_remove_one() unregisters and frees resources owned by the net_device, including the DMA block, MMIO mapping, PCI regions, and the net_device itself. gem_init_one() then falls through to its own cleanup labels and frees the same resources again. Keep the register_netdev() error path in gem_init_one(): clear drvdata so PM/remove paths do not see a half-registered device, remove the NAPI instance added during probe, and let the existing cleanup labels release the resources once. The issue was found by a local static-analysis checker for probe error paths. The reported path was manually inspected before sending this fix. Compile-tested with CONFIG_SUNGEM=y. Runtime testing was not performed because no sungem hardware is available.

GHSA-HMG3-FX9R-3V68

Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-17 06:33

Details

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

net: sungem: fix probe error cleanup

gem_init_one() calls gem_remove_one() when register_netdev() fails. gem_remove_one() unregisters and frees resources owned by the net_device, including the DMA block, MMIO mapping, PCI regions, and the net_device itself. gem_init_one() then falls through to its own cleanup labels and frees the same resources again.

Keep the register_netdev() error path in gem_init_one(): clear drvdata so PM/remove paths do not see a half-registered device, remove the NAPI instance added during probe, and let the existing cleanup labels release the resources once.

The issue was found by a local static-analysis checker for probe error paths. The reported path was manually inspected before sending this fix.

Compile-tested with CONFIG_SUNGEM=y. Runtime testing was not performed because no sungem hardware is available.

Severity

7.8 (High)
