What is CVE-2026-74292?
CVE-2026-74292 is a high-severity memory corruption vulnerability in Linux, published on 15 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:
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.
