  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: bpf_local_storage: Always use bpf_mem_alloc in PREEMPT_RT\n\nIn PREEMPT_RT, kmalloc(GFP_ATOMIC) is still not safe in non preemptible\ncontext. bpf_mem_alloc must be used in PREEMPT_RT. This patch is\nto enforce bpf_mem_alloc in the bpf_local_storage when CONFIG_PREEMPT_RT\nis enabled.\n\n[   35.118559] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48\n[   35.118566] in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1832, name: test_progs\n[   35.118569] preempt_count: 1, expected: 0\n[   35.118571] RCU nest depth: 1, expected: 1\n[   35.118577] INFO: lockdep is turned off.\n    ...\n[   35.118647]  __might_resched+0x433/0x5b0\n[   35.118677]  rt_spin_lock+0xc3/0x290\n[   35.118700]  ___slab_alloc+0x72/0xc40\n[   35.118723]  __kmalloc_noprof+0x13f/0x4e0\n[   35.118732]  bpf_map_kzalloc+0xe5/0x220\n[   35.118740]  bpf_selem_alloc+0x1d2/0x7b0\n[   35.118755]  bpf_local_storage_update+0x2fa/0x8b0\n[   35.118784]  bpf_sk_storage_get_tracing+0x15a/0x1d0\n[   35.118791]  bpf_prog_9a118d86fca78ebb_trace_inet_sock_set_state+0x44/0x66\n[   35.118795]  bpf_trace_run3+0x222/0x400\n[   35.118820]  __bpf_trace_inet_sock_set_state+0x11/0x20\n[   35.118824]  trace_inet_sock_set_state+0x112/0x130\n[   35.118830]  inet_sk_state_store+0x41/0x90\n[   35.118836]  tcp_set_state+0x3b3/0x640\n\nThere is no need to adjust the gfp_flags passing to the\nbpf_mem_cache_alloc_flags() which only honors the GFP_KERNEL.\nThe verifier has ensured GFP_KERNEL is passed only in sleepable context.\n\nIt has been an old issue since the first introduction of the\nbpf_local_storage ~5 years ago, so this patch targets the bpf-next.\n\nbpf_mem_alloc is needed to solve it, so the Fixes tag is set\nto the commit when bpf_mem_alloc was first used in the bpf_local_storage.",
