CVE-2026-97567

A flaw was found in the Linux kernel's MultiPath TCP MPTCP subsystem. A race condition can occur between socket disconnection and packet retransmission timer handling, resulting in an inconsistent socket state. A local user can exploit this timing flaw during active connection teardown to cause a...

ROS-20260929-73-0171

The vulnerability of the net/mptcp/subflow.c component in the Linux operating system is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to cause a service failure...

ROS-20260929-73-0196

The vulnerability of the mptcpretrans function in the net/mptcp/protocol.c module of the MPTCP protocol implementation in Linux’s kernel is related to the occurrence of mutual locking. Exploiting this vulnerability could allow a attacker to compromise the confidentiality, integrity, and...

CVE-2026-97524

A flaw was found in the Linux kernel's MultiPath TCP MPTCP subsystem. Under specific network error and subflow reset conditions during data receive operations, the kernel can enter a recursive call loop that attempts to acquire an already-held data lock. A remote attacker communicating over an...

CVE-2026-97523

A flaw was found in the Linux kernel's MultiPath TCP MPTCP subsystem. A race condition between the packet scheduler and socket state transitions can cause the maximum segment size to be reset to zero following a transmission failure. An attacker could exploit this flaw during connection handling ...

CVE-2026-97522

A flaw was found in the Linux kernel's MultiPath TCP MPTCP subsystem. When an error occurs while pushing pending data across subflows, the kernel improperly updates the transmitted byte counter with a negative error code instead of only accounting for successful transmissions. This accounting...

ROS-20260928-73-0064

The vulnerability of the mptcpschedulework function in the net/mptcp/protocol.c module of the MPTCP protocol implementation in the Linux operating system is related to synchronization errors when using shared resources „Race Conditions“.
