# CVE-2026-68413: wifi: ipw2100: fix potential memory leak in ipw2100_pci_init_one()

Status: published. Published: 2026-08-10. Updated: 2026-11-06.

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

wifi: ipw2100: fix potential memory leak in ipw2100_pci_init_one()

The memory allocated in the ipw2100_alloc_device() function is not freed
in some of the error paths in ipw2100_pci_init_one(). Fix that by
converting the direct return into a goto to the error path return.

The error path when pci_enable_device() fails cannot jump to fail, since
at this point priv is not set, so perform error handling inline.
