CVE-2024-50171

CVE-2024-50171 affects the Linux kernel BCM SYSPORT driver: bcm_sysport_xmit() can leak memory because skb is not freed when dma_map_single() fails, with a fix that frees the skb via dev_kfree_skb() and returns NETDEV_TX_OK. Public records indicate the issue is resolved in patched kernel releases...

CVE-2024-50168

CVE-2024-50168 affects the Linux kernel component net/sun3_82586. A memory leak could occur in sun3_82586_send_packet() when skb->len is too long, as the function previously returned NETDEV_TX_OK without freeing the socket buffer (skb). The fix adds dev_kfree_skb() to free the skb in that code...
