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

octeontx2-af: CGX: fix bitmap leaks

The RX/TX flow-control bitmaps (rx_fc_pfvf_bmap and tx_fc_pfvf_bmap)
are allocated by cgx_lmac_init() but never freed in cgx_lmac_exit().
Unbinding and rebinding the driver therefore triggers kmemleak:

unreferenced object (size 16):
backtrace:
rvu_alloc_bitmap
cgx_probe

Free both bitmaps during teardown.
