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.

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...
