vulnerability has been resolved:\n\nautofs: fix sbi->pipe file reference leak in autofs_kill_sb()\n\nWhen autofs_fill_super() fails before clearing AUTOFS_SBI_CATATONIC (for\nexample, when find_get_pid() fails on an invalid pgrp mount option, or\nwhen an fs_context is closed before mounting), deactivate_locked_super()\ninvokes autofs_kill_sb() -> autofs_catatonic_mode(sbi).\n\nBecause AUTOFS_SBI_CATATONIC is still set in sbi->flags,\nautofs_catatonic_mode() returns early without calling fput(sbi->pipe),\npermanently leaking the pipe struct file reference.\n\nExplicitly release sbi->pipe in autofs_kill_sb() if it is still non-NULL\nafter autofs_catatonic_mode().","categories":["Operating
