CVE-2026-72393

A flaw was found in the Linux kernel's fbnic Ethernet driver. When the fbnictxlso function reallocates a socket buffer skb, it fails to update a cached pointer to shared information. This can lead to a use-after-free vulnerability, where the driver attempts to access memory that has already been...

CVE-2026-72393

The CVE-2026-72393 issue affects the Linux kernel’s fbnic path for Ethernet devices. The bug arises in fbnic_tx_lso where skb_cow_head() may reallocate the skb and its shared info, causing a use-after-free by tracing a 4-byte read inside a freed skb region. This is a network-attack surface via UD...

CVE-2026-45952

A flaw was found in the Linux kernel's fbnic driver. This vulnerability allows a local user to cause a Denial of Service DoS by increasing the Maximum Transmission Unit MTU beyond the hardware's threshold while an eXpress Data Path XDP program is attached. This improper validation of MTU changes...
