CVE-2022-49330

The CVE-2022-49330 issue affects the Linux kernel's MTU probing logic in net/ipv4/tcp_input.c. Specifically, tcp_mtu_probe() starts an MTU probe only when tcp_snd_cwnd(tp) is >= 11, but tcp_snd_cwnd(tp) can later be reduced before the probe completes, creating a scenario that could lead to a z...

kernel: tcp: avoid too many retransmit packets

A vulnerability was found in the tcpretransmittimer function in the Linux kernel's TCP implementation. This issue occurs when a TCP socket uses TCPUSERTIMEOUT and the peer's window retracts to zero, leading to excessive retransmission of packets every two milliseconds for up to four minutes after...
