And indeed\nit will, some 0.4% of times this code is called.\n\nThen enqueue + 1 is an invalid pointer. It will crash the kernel right\naway or load some junk which may look like a link TRB and cause the real\nlink TRB to be replaced with a NOOP. This wouldn't end well.\n\nUse a functionally equivalent test which doesn't dereference the pointer\nand always gives correct result.\n\nSomething has crashed my machine twice in recent days while playing with\nan Etron HC, and a control transfer stress test ran for confirmation has\njust crashed it again. The same test passes with this patch applied.","state":0,"publishedAt":"2025-05-08T06:26:10+00:00","modifiedAt":"2026-10-15T21:52:00.5+00:00","affected":[{"ecosystem":"Vendor
