CVE-2026-72406

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A double-free issue exists in the sungem network driver. When the register netdev() function fails, the gem init one() function calls gem remove one(), which unregisters and frees resources including the DMA block, MMIO mapping, PCI regions, and the net device. Subsequently, gem init one() continues to its own cleanup labels, attempting to free the same resources a second time.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
