- Summary
- ipvs: Defer ip_vs_ftp unregister during netns cleanup
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ipvs: Defer ipvsftp unregister during netns cleanup
On the netns cleanup path, _ipvsftpexit() may unregister ipvsftp before connections with valid cp->app pointers are flushed, leading to a use-after-free.
Fix this by introducing a global
exiting_moduleflag, set to true in ipvsftpexit() before unregistering the pernet subsystem. In _ipvsftpexit(), skip ipvsftp unregister if called during netns cleanup (when exitingmodule is false) and defer it to _ipvscleanupbatch(), which unregisters all apps after all connections are flushed. If called during module exit, unregister ipvsftp immediately. - Database specific
