Simple program to remove a module from the Linux Kernel.
Syntax
rmmod [ -f ] [ -w ] [ -s ] [ -v ] [ modulename ]
Key
-f --force
This option can be extremely dangerous: it has no effect unless CONFIG_MODULE_FORCE_UNLOAD was set
when the kernel was compiled. With this option, you can remove modules which are being used, or
which are not designed to be removed, or have been marked as unsafe (see lsmod(8)).
-s --syslog
Send errors to syslog instead of standard error.
-v --verbose
Print messages about what the program is doing.
Usually rmmod prints messages only if something goes wrong.
-V --version
Show the version of rmmod and exit.
-w --wait
Normally, rmmod will refuse to unload modules which are in use. With this option,
rmmod will isolate the module, and wait until the module is no longer used.
Nothing new will be able to use the module, but it's up to you to make sure the current users
eventually finish with it. See lsmod(8)) for information on usage counts.
Blacklist the algif_aead module to mitigate the Copy Fail scratch-write bug CVE-2026-31431:
rmmod algif_aead 2>/dev/null
