Description
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.
