Description OSIDB Bzimport 2024-10-21 13:03:01 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mvm: set the cipher for secured NDP ranging

The cipher pointer is not set, but is derefereced trying to set its
content, which leads to a NULL pointer dereference.
Fix it by pointing to the cipher parameter before dereferencing.
