CVE-2026-46041
Description
A flaw was found in the Linux kernel's greybus subsystem. This vulnerability occurs when a function attempts to pause its execution while holding a critical system lock, a condition known as 'sleep in atomic context'. This improper handling can lead to a system crash, making the system unavailable and resulting in a Denial of Service (DoS).
