CVE-2023-54110: usb: rndis_host: Secure rndis_query check against int overflow

• Severity: unknown
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

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.

Affected products

• Linux kernel: 2.6.22 — fixed in 6.2

How to fix

Upgrade to a fixed version: Linux kernel 6.2. Check the vendor advisory for mitigations.
