CVE-2026-23331 udp: Unhash auto-bound connected sk from 4-tuple hash table when disconnected.

In the Linux kernel, the following vulnerability has been resolved: udp: Unhash auto-bound connected sk from 4-tuple hash table when disconnected. Let's say we bind an UDP socket to the wildcard address with a non-zero port, connect it to an address, and disconnect it from the address. bind sets...

CVE-2026-23331

The CVE-2026-23331 issue concerns the Linux kernel UDP 4-tuple hash table: when an auto-bound UDP socket is bound, connected, and then disconnected, the socket may be moved to a new hash slot without removing the old entry, leaving garbage in the 4-tuple chain. The fix is to remove such a socket ...

CVE-2026-23302

Summary (CVE-2026-23302): The Linux kernel patch resolves a data-race in data-path pointers sk->sk_data_ready and sk->sk_write_space, where skmsg and possibly other layers could modify these pointers while others may read them concurrently. The fix adds corresponding READ_ONCE()/WRITE_ONCE(...

CVE-2026-23302 net: annotate data-races around sk->sk_{data_ready,write_space}

In the Linux kernel, the following vulnerability has been resolved: net: annotate data-races around sk-skdataready,writespace skmsg and probably other layers are changing these pointers while other cpus might read them concurrently.
