CVE-2024-50083 is a high-severity vulnerability in the Linux kernel's Multipath TCP (MPTCP) implementation. It involves corruption of the Data Sequence Signal (DSS) due to large Path Maximum Transmission Unit (PMTU) transmissions. The flaw was discovered through fuzzing with Syzkaller, which triggered a kernel warning and potential instability. This vulnerability can cause denial of service by crashing or destabilizing the kernel during TCP operations involving MPTCP subflows.
