"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncgroup/cpuset: Don't access cpuset_cgrp_subsys.root in is_in_v2_mode()\n\nAfter seeing the patch [1] to guard is_in_v2_mode() with RCU, it makes\nme realize that is_in_v2_mode() may be called in a context where a new\ncgroup filesystem is being rebound with stale cpuset_cgrp_subsys.root\npointer. Avoid this potential UaF situation by adding a new cpuset_v2_mode\nflag which is set when the cpuset_v2_mode mount option is used. This\nflag is written into only when cpuset_bind() is being called with a\nstable cpuset_cgrp_subsys.root value. The is_in_v2_mode() helper is\nmodified to read the new cpuset_v2_mode flag instead of accessing\ncpuset_cgrp_subsys.root directly.\n\n[1] https://lore.kernel.org/lkml/20260929084124.626693-2-arighi@nvidia.com"
