      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmemcg: use round-robin victim selection in refill_stock\n\nHarry Yoo reported that get_random_u32_below() is not safe to call in the\nnmi context and memcg charge draining can happen in nmi context.\n\nMore specifically get_random_u32_below() is neither reentrant- nor\nNMI-safe: it acquires a per-cpu local_lock via local_lock_irqsave() on the\nbatched_entropy_u32 state.  An NMI that lands on a CPU mid-update of the\nChaCha batch state and recurses into the random subsystem would corrupt\nthat state.  The memcg_stock local_trylock prevents re-entry on the percpu\nstock itself, but cannot protect an unrelated subsystem's per-cpu lock.\n\nReplace the random pick with a per-cpu round-robin counter stored in\nmemcg_stock_pcp and serialized by the same local_trylock that already\nguards cached[] and nr_pages[].  No atomics, no random calls, no extra\nlocks needed.",
