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...

CVE-2025-37807

CVE-2025-37807 is a Linux kernel issue in the BPF percpu hashmap path where a percpu pointer is stored at an 8-byte aligned location only if the key_size rounds up to 8; otherwise a 4-byte aligned location is used, causing kmemleak to miss the pointer and report a leak. The root cause is an align...
