"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject sleepable kprobe_multi programs at attach time\n\nkprobe.multi programs run in atomic/RCU context and cannot sleep.\nHowever, bpf_kprobe_multi_link_attach() did not validate whether the\nprogram being attached had the sleepable flag set, allowing sleepable\nhelpers such as bpf_copy_from_user() to be invoked from a non-sleepable\ncontext.\n\nThis causes a \"sleeping function called from invalid context\" splat:\n\n BUG: sleeping function called from invalid context at ./include/linux/uaccess.h:169\n in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1787, name: sudo\n preempt_count: 1, expected: 0\n RCU nest depth: 2, expected: 0\n\nFix this by rejecting sleepable programs early in\nbpf_kprobe_multi_link_attach(), before any further processing."
