Description

In the Linux kernel, the following vulnerability has been resolved:

eth: fbnic: Handle maximum standalone channels

Standalone channels use one NAPI vector for each Tx and Rx queue. fbnic's allocation path excludes FBNIC_MAX_TXQS from that layout. A 64-Tx/64-Rx configuration therefore records 128 vectors but allocates only 64, leaving NULL entries that resource setup dereferences.

Include the maximum vector count in standalone allocation.
