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