Description OSIDB Bzimport 2025-12-24 14:04:43 UTC 
In the Linux kernel, the following vulnerability has been resolved:

usb: rndis_host: Secure rndis_query check against int overflow

Variables off and len typed as uint32 in rndis_query function
are controlled by incoming RNDIS response message thus their
value may be manipulated. Setting off to a unexpectetly large
value will cause the sum with len and 8 to overflow and pass
the implemented validation step. Consequently the response
pointer will be referring to a location past the expected
buffer boundaries allowing information leakage e.g. via
RNDIS_OID_802_3_PERMANENT_ADDRESS OID.
