Description OSIDB Bzimport 2025-06-18 12:01:38 UTC 
In the Linux kernel, the following vulnerability has been resolved:

staging: rtl8712: fix use after free bugs

_Read/Write_MACREG callbacks are NULL so the read/write_macreg_hdl()
functions don't do anything except free the "pcmd" pointer.  It
results in a use after free.  Delete them.
