CVE-2023-53863

CVE-2023-53863 : In the Linux kernel, netlink fdb dumps previously hard-coded device address length using ETH_ALEN instead of the device’s addr_len. This can expose an information leak (notably kernel-infoleak paths) in scenarios where a netdev device reports an addr_len different from six. The a...
