AZL-56337 CVE-2025-21666 affecting package kernel for versions less than 5.15.180.1-1
In the Linux kernel, the following vulnerability has been resolved: vsock: prevent null-ptr-deref in vsockhasdata|hasspace Recent reports have shown how we sometimes call vsockhasdata when a vsock socket has been de-assigned from a transport see attached links, but we shouldn't. Previous commits...

UBUNTU-CVE-2025-21669
In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: discard packets if the transport changes If the socket has been de-assigned or assigned to another transport, we must discard any packets received because they are not expected and would cause issues when we access...
UBUNTU-CVE-2025-21670
In the Linux kernel, the following vulnerability has been resolved: vsock/bpf: return early if transport is not assigned Some of the core functions can only be called if the transport has been assigned. As Michal reported, a socket might have the transport at NULL, for example after a failed...

CVE-2025-21670
CVE-2025-21670 affects the Linux kernel’s vsock/bpf path. The issue occurs when vsock_transport is not assigned (NULL) during vsock_bpf_recvmsg for connected sockets (stream/seqpacket), leading to a NULL pointer dereference in vsock_connectible_has_data and an in-kernel oops trace. The vulnerabil...

CVE-2025-21666
CVE-2025-21666 involves a null-pointer dereference in the Linux kernel when vsock_*_has_data/has_space is invoked on a socket that has been de-assigned from a transport. The problem is mitigated by returning 0 (no space/data) with a warning to keep execution stable. Connected documents confirm th...
