CVE-2026-43157
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.
