What it is

In the Linux kernel, the following vulnerability has been resolved:

autofs: fix sbi->pipe file reference leak in autofs_kill_sb()

When autofs_fill_super() fails before clearing AUTOFS_SBI_CATATONIC (for

example, when find_get_pid() fails on an invalid pgrp mount option, or

when an fs_context is closed before mounting), deactivate_locked_super()

invokes autofs_kill_sb() -> autofs_catatonic_mode(sbi).

Because AUTOFS_SBI_CATATONIC is still set in sbi->flags,

autofs_catatonic_mode() returns early without calling fput(sbi->pipe),

permanently leaking the pipe struct file reference.

Explicitly release sbi->pipe in autofs_kill_sb() if it is still non-NULL

after autofs_catatonic_mode().
