GHSA-86V6-C9P3-RM2J

Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-17 06:33

Details

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.

Severity

7.1 (High)
