-Subject: bpf: fix double-fdput in replace_map_fd_with_map_ptr()
-
-When bpf(BPF_PROG_LOAD, ...) was invoked with a BPF program whose bytecode
-references a non-map file descriptor as a map file descriptor, the error
-handling code called fdput() twice instead of once (in __bpf_map_get() and
-in replace_map_fd_with_map_ptr()). If the file descriptor table of the
-current task is shared, this causes f_count to be decremented too much,
-allowing the struct file to be freed while it is still in use
-(use-after-free). This can be exploited to gain root privileges by an
-unprivileged user.
-
-This bug was introduced in
-commit 0246e64d9a5f ("bpf: handle pseudo BPF_LD_IMM64 insn"), but is only
-exploitable since
-commit 1be7f75d1668 ("bpf: enable non-root eBPF programs") because
-previously, CAP_SYS_ADMIN was required to reach the vulnerable code.
