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...

The vulnerability of the __mptcp_close_ssk() function in the net/mptcp/protocol.c module of the MPTCP protocol implementation in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the mptcpclosessk function in the net/mptcp/protocol.c module of the MPTCP protocol implementation in the Linux operating system is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the...
