What is CVE-2026-68413?
CVE-2026-68413 is a memory corruption vulnerability in Linux, published on 10 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
