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-2026-23310

Summary: CVE-2026-23310 affects the Linux kernel bonding/kern XDP path. If a bond is in 802.3ad or balance-xor mode and an XDP program is loaded, changing xmit_hash_policy to vlan+srcmac can escape the existing guard, leaving bond->xdp_prog set and causing an incompatible state during tear-dow...

Towards Remote Attestation of Microarchitectural Attacks: The Case of Rowhammer

Microarchitectural vulnerabilities increasingly undermine the assumption that hardware can be treated as a reliable root of trust. Prevention mechanisms often lag behind evolving attack techniques, leaving deployed systems unable to assume continued trustworthiness. We propose a shift from...
