In the Linux kernel, the following vulnerability has been resolved:

netfilter: nftables: reject duplicate device on updates

A chain/flowtable update with duplicated devices in the same batch is possible. Unfortunately, netdev event path only removes the first device that is found, leaving unregistered the hook of the duplicated device.

Check if a duplicated device exists in the transaction batch, bail out with EEXIST in such case.

WARNING is hit when unregistering the hook:

[49042.221275] WARNING: CPU: 4 PID: 8425 at net/netfilter/core.c:340 nfhookentryhead+0xaa/0x150 [49042.221375] CPU: 4 UID: 0 PID: 8425 Comm: nft Tainted: G S 6.16.0+ #170 PREEMPT(full) [...] [49042.221382] RIP: 0010:nfhookentryhead+0xaa/0x150
