Doc Text:	A flaw was found in the Linux kernel's `au1200fb` framebuffer driver. When the `platform_get_irq` function fails during the `au1200fb_drv_probe` process, the driver incorrectly returns an error without releasing allocated memory. This memory leak could be exploited by a local attacker, potentially leading to a Denial of Service (DoS) due to resource exhaustion.	Story Points:	---

Description OSIDB Bzimport 2026-05-27 15:13:30 UTC

In the Linux kernel, the following vulnerability has been resolved:

fbdev: au1200fb: Fix a memory leak in au1200fb_drv_probe()

In au1200fb_drv_probe(), when platform_get_irq fails(), it directly
returns from the function with an error code, which causes a memory
leak.

Replace it with a goto label to ensure proper cleanup.
