  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/nouveau/clk: fix list cursor use after loop in nvkm_clk_ustate_update  If list_for_each_entry() exits without hitting a break then \"pstate\" is not a valid pstate pointer.  Introduce a \"found\" variable instead.  The check is reachable from userspace: nvkm_clk_ustate_update() takes the pstate id straight from the 'pstate' debugfs file, so requesting an id that is not in clk-\u003estates - or any id at all when the perf tables are broken and the list is empty - makes the pstate-\u003epstate != req test dereference the list head cast to a struct nvkm_pstate, which is an out-of-bounds read.
