CVE-2026-43397

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/bridge: samsung-dsim: Fix memory leak in error path<br /> <br /> In samsung_dsim_host_attach(), drm_bridge_add() is called to add the<br /> bridge. However, if samsung_dsim_register_te_irq() or<br /> pdata-&gt;host_ops-&gt;attach() fails afterwards, the function returns<br /> without removing the bridge, causing a memory leak.<br /> <br /> Fix this by adding proper error handling with goto labels to ensure<br /> drm_bridge_remove() is called in all error paths. Also ensure that<br /> samsung_dsim_unregister_te_irq() is called if the attach operation<br /> fails after the TE IRQ has been registered.<br /> <br /> samsung_dsim_unregister_te_irq() function is moved without changes<br /> to be before samsung_dsim_host_attach() to avoid forward declaration.
