CVE-2026-43157

Summary: CVE-2026-43157 affects the Linux kernel octeontx2-af CGX driver. The RX/TX flow-control bitmaps (rx_fc_pfvf_bmap, tx_fc_pfvf_bmap) are allocated during cgx_lmac_init() but not freed during cgx_lmac_exit(), enabling a kernel memory leak (kmemleak) when the driver is unbound and rebound. I...
