CVE-2026-43397

A flaw was found in the Linux kernel's drm/bridge: samsung-dsim module. Improper error handling in the samsung_dsim_host_attach() function can lead to a memory leak. If the drm_bridge_add() operation is successful but subsequent operations fail, the bridge is not properly removed, causing memory to be retained. Over time, this unreleased memory can accumulate, potentially leading to a Denial of Service (DoS) condition where the system becomes unstable or unresponsive.
