"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing/fprobe: Fix NULL pointer dereference in fprobe_fgraph_entry()\n\nfprobe_fgraph_entry() sizes a shadow-stack reservation in one walk of\nthe per-ip fprobe list and fills it in a second walk, both under\nrcu_read_lock() only. A fprobe registered on an already-live ip can\nbecome visible between the two walks, so the fill walk processes an\nexit_handler the sizing walk did not count and used runs past\nreserved_words. If the sizing walk counted nothing, fgraph_data is NULL\nand the first write_fprobe_header() faults:\n\n Oops: general protection fault, probably for non-canonical address ...\n KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n RIP: 0010:fprobe_fgraph_entry+0xa38/0xf10 kernel/trace/fprobe.c:167\n Call Trace:\n <TASK>\n function_graph_enter_regs+0x44c/0xa10 kernel/trace/fgraph.c:677\n ftrace_graph_func+0xc5/0x140 arch/x86/kernel/ftrace.c:671\n __kernel_text_address+0x9/0x40 kernel/extable.c:78\n arch_stack_walk+0x117/0x170 arch/x86/kernel/stacktrace.c:26\n kmem_cache_free+0x188/0x580 mm/slub.c:6378\n tcp_data_queue+0x18d/0x6550 net/ipv4/tcp_input.c:5590\n [...]\n </TASK>\n\nThe list cannot be frozen across the two walks, so skip a node that does\nnot fit the reservation and count it as missed."
