CVE-2026-72269: fbdev: uvesafb: fix potential memory leak in uvesafb_probe()

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@kernel.org>

Description
===========

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

fbdev: uvesafb: fix potential memory leak in uvesafb_probe()

Due to an incorrect goto label, memory allocated for modedb and modelist
in uvesafb_vbe_init() is not freed in some error paths. Fix this by
updating the goto label.

The Linux kernel CVE team has assigned CVE-2026-72269 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:
