CVE-2026-43457

CVE-2026-43457 affects the Linux kernel MCTP over I2C receive path. When midev->allow_rx is false, a newly allocated skb is not consumed by netif_rx() and must be freed directly, otherwise a memory leak can occur leading to potential DoS through memory exhaustion. The available connected sourc...

CVE-2026-43455

In CVE-2026-43455, multiple sources confirm a race in the Linux kernel MCTP module: mctp_flow_prepare_output() checks key->dev and may call mctp_dev_set_key() without holding key->lock, while both mctp_dev_set_key() and mctp_dev_release_key() require the lock. This can allow concurrent path...

CVE-2026-43375

CVE-2026-43375 concerns the Linux kernel in the MCTP path. A leak occurs during probe failures because the driver saves a reference to the USB device but fails to release it on error paths. The fix drops the redundant device reference to prevent memory leaks when the probe fails, simplifying driv...
