Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.8.0-rc4-syzkaller-00212-g40b9385dd8e6 Description The vulnerability is related to a possible deadlock in the subflow diag of the mptcp component in the Linux kernel. This issue can be exploited to cause a denia...

PT-2024-8467

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to errors in resource management within the subflow finish connect function of the mptcp component in the Linux kernel. This may allow an attacker to cause a denial ...

PT-2024-14741

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.0-rc5-gcd8bdf563d46 Description The issue arises from the TCP sockets and MPTCP subflows building egress packets larger than 64K, exceeding the maximum DSS data size. This results in the length being...

kernel: mptcp: use proper req destructor for IPv6

A flaw was discovered in the Linux kernel’s Multipath TCP MPTCP implementation where the wrong destructor function was used for IPv6 subflow request sockets. Previously, even when handling IPv6 MPTCP subflows, only the IPv4 request socket destructor was invoked, leaving IPv6-specific fields...
