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

[Greg Kroah-Hartman]

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.

The Linux kernel CVE team has assigned CVE-2026-68413 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
