CVE-2025-37788 Information

Description

In the Linux kernel the following vulnerability has been resolved:

cxgb4: fix memory leak in cxgb4_init_ethtool_filters() error path

In the for loop used to allocate the loc_array and bmap for each port a memory leak is possible when the allocation for loc_array succeeds but the allocation for bmap fails. This is because when the control flow goes to the label free_eth_finfo only the allocations starting from (i-1)th iteration are freed.

Fix that by freeing the loc_array in the bmap allocation error path.
