CVE-2024-41007

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...
