Hello,
Our static analysis tool finds a possible null-pointer dereference in
rtllib_wx.c in Linux 5.14.0-rc3:
The variable (*crypt)->ops is checked in:
342: if (*crypt && (*crypt)->ops && strcmp((*crypt)->ops->name,
"R-WEP") != 0)
This indicates that it can be NULL. If so, null-pointer dereferences
will occur:
389: (*crypt)->ops->set_key()
400: len = (*crypt)->ops->get_key()
I am not quite sure whether this possible null-pointer dereference is
real and how to fix it if it is real.
Any feedback would be appreciated, thanks!
