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.
