Summary
CVE-2026-23278 affecting package kernel for versions less than 6.6.144.1-1
Details

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

netfilter: nf_tables: always walk all pending catchall elements

During transaction processing we might have more than one catchall element: 1 live catchall element and 1 pending element that is coming as part of the new batch.

If the map holding the catchall elements is also going away, its required to toggle all catchall elements and not just the first viable candidate.

Otherwise, we get: WARNING: ./include/net/netfilter/nftables.h:1281 at nftdatarelease+0xb7/0xe0 [nftables], CPU#2: nft/1404 RIP: 0010:nftdatarelease+0xb7/0xe0 [nf_tables] [..] _nftsetelemdestroy+0x106/0x380 [nftables] nftablesabortrelease+0x348/0x8d0 [nftables] nftablesabort+0xcf2/0x3ac0 [nftables] nfnetlinkrcvbatch+0x9c9/0x20e0 [..]
