  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Fix WARNING in bpf_tracing_link_release  The trampoline could be corrupted by the blindly 'tr-\u003eflags = BPF_TRAMP_F_TAIL_CALL_CTX' in verifier.  1. A fexit attached to a tail_call_reachable prog. 'tr-\u003eflags' became    'BPF_TRAMP_F_CALL_ORIG | BPF_TRAMP_F_TAIL_CALL_CTX'. And, the    trampoline would poke the target prog's nop insn using jmp insn instead    of call insn. 2. Another fexit loaded with the same tail_call_reachable prog target.    'tr-\u003eflags' became 'BPF_TRAMP_F_TAIL_CALL_CTX'. 3. Close the first fexit link. Due to no BPF_TRAMP_F_CALL_ORIG in    'tr-\u003eflags', the trampoline will fail to restore the prog's nop insn    using call insn.
