Vulnerability Title
net: sungem: fix probe error cleanup
来源: CVE Program / CVE List V5
Vulnerability Description
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.

Linux kernel 安全漏洞
来源: 中国国家信息安全漏洞库 CNNVD
Vulnerability Description
Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 2.6.12版本存在安全漏洞，该漏洞源于net: sungem驱动在register_netdev()失败时调用gem_remove_one()释放资源后，又继续执行自身清理逻辑重复释放相同资源，可能导致双重释放。
