Subject: [PATCH] efi: payload: bootm: fix memory corruption on initrd load error
Date: Mon, 9 Feb 2026 16:30:46 +0100 [thread overview]
Message-ID: <20260209153047.1842593-1-a.fatoum@pengutronix.de> (raw)
initrd is a pointer to a pointer and its only used place the pointed at
pointer on stack. Freeing it will this trigger memory corruption.
Fix this by actually freeing the heap buffer.
