"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/nouveau/clk: fix list cursor use after loop in nvkm_clk_ustate_update\n\nIf list_for_each_entry() exits without hitting a break then \"pstate\" is\nnot a valid pstate pointer. Introduce a \"found\" variable instead.\n\nThe check is reachable from userspace: nvkm_clk_ustate_update() takes the\npstate id straight from the 'pstate' debugfs file, so requesting an id\nthat is not in clk->states - or any id at all when the perf tables are\nbroken and the list is empty - makes the pstate->pstate != req test\ndereference the list head cast to a struct nvkm_pstate, which is an\nout-of-bounds read.\n\n[Francesco: rebased on drm-misc-next, expanded the commit message]"
