kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

In the Linux kernel, the following vulnerability has been resolved: net: fixed a memory leak in tcpconnrequest. If inetcskreqskqueuehashadd returns false, tcpconnrequest will return without freeing the dst memory, which was allocated in afops-routereq. Here is the stack trace for the issue:...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: inet: inetdefrag: prevent sk release while still in use The functions iplocalout and others can pass skb-sk as a function argument. If the skb is a fragment and reassembly occurs before such a function call returns, the sk must n...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In mptcp, the task of cleaning up subflows has been moved to mptcpDestroyCommon. If the creation of a mptcp socket fails due to the CGROUPINETSOCKCREATE eBPF program, the MPTCP protocol ends up leaking all subflows. This related...
