  "description": "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 \u0027tr-\u003Eflags = BPF_TRAMP_F_TAIL_CALL_CTX\u0027 in verifier.  1. A fexit attached to a tail_call_reachable prog. \u0027tr-\u003Eflags\u0027 became    \u0027BPF_TRAMP_F_CALL_ORIG | BPF_TRAMP_F_TAIL_CALL_CTX\u0027. And, the    trampoline would poke the target prog\u0027s nop insn using jmp insn instead    of call insn. 2. Another fexit loaded with the same tail_call_reachable prog target.    \u0027tr-\u003Eflags\u0027 became \u0027BPF_TRAMP_F_TAIL_CALL_CTX\u0027. 3. Close the first fexit link. Due to no BPF_TRAMP_F_CALL_ORIG in    \u0027tr-\u003Eflags\u0027, the trampoline will fail to restore the prog\u0027s nop insn    using call insn.
