SUSE CVE-2023-54176

In the Linux kernel, the following vulnerability has been resolved: mptcp: stricter state check in mptcpworker As reported by Christoph, the mptcp protocol can run the worker when the relevant msk socket is in an unexpected state: connect // incoming reset + fastclose // the mptcp worker is...

CVE-2023-54176

Mode C: Concrete details present. CVE-2023-54176 affects the Linux kernel MPTCP path where mptcp_worker could run while the msk socket was in an unexpected state (connect/fastclose sequence leading to a partition crash). The fix implements a stricter state check in mptcp_worker by preventing exec...

CVE-2022-50071

In the Linux kernel, the following vulnerability has been resolved: mptcp: move subflow cleanup in mptcpdestroycommon If the mptcp socket creation fails due to a CGROUPINETSOCKCREATE eBPF program, the MPTCP protocol ends-up leaking all the subflows: the related cleanup happens in mptcpdestroysock...

CVE-2022-50071

The CVE-2022-50071 issue affects the Linux kernel’s MPTCP implementation. The vulnerability arises when socket creation fails due to a CGROUP_INET_SOCK_CREATE eBPF program, causing leakage of subflows because cleanup was not invoked in that code path. The fix moves subflow cleanup into the mptcp_...

UBUNTU-CVE-2022-49775

In the Linux kernel, the following vulnerability has been resolved: tcp: cdg: allow tcpcdgrelease to be called multiple times Apparently, mptcp is able to call tcpdisconnect on an already disconnected flow. This is generally fine, unless current congestion control is CDG, because it might trigger...

CVE-2022-49775

CVE-2022-49775 (Linux kernel) affects the tcp_cdg congestion control. The advisory notes that when MPTCP calls tcp_disconnect() on an already-disconnected flow under CDG, it may trigger a double-free in the SLAB allocator. The vulnerability arises from the ability to call tcp_cdg_release() multip...
