CVE-2026-74292: ASoC: tegra: tegra210_ahub: Validate written enum value

[Greg Kroah-Hartman]

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

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

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

ASoC: tegra: tegra210_ahub: Validate written enum value

tegra_ahub_put_value_enum() reads e->values[item[0]] before
checking whether item[0] is within the enum item range. The existing
check therefore happens too late to prevent an out-of-range read of the
values array.

Move the check before the array access.

The Linux kernel CVE team has assigned CVE-2026-74292 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:
