kernel: dccp: crash while sending ipv6 reset packet

It was found that the Linux kernel's Datagram Congestion Control Protocol DCCP implementation used the IPv4-only inetskrebuildheader function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system...

Qemu: net: out of bounds read in net_checksum_calculate()

An out-of-bounds read-access flaw was found in the QEMU emulator built with IP checksum routines. The flaw could occur when computing a TCP/UDP packet's checksum, because a QEMU function used the packet's payload length without checking against the data buffer's size. A user inside a guest could...

kernel: use after free in dccp protocol

A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol DCCP implementation freed SKB socket buffer resources for a DCCPPKTREQUEST packet when the IPV6RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the...
