Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: tcpbpf: The return value of tcpbpfsendmsg was corrected. When we use the cork mechanism in psock-cork, the last message triggers flushing, resulting in sending a skmsg that is larger than the current message size. In this case, i...

Kernel: net: panic while pushing pending data out of a IPv6 socket with UDP_CORK enabled

The udpv6pushpendingframes function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service BUG and system crash via a crafted application that uses the UDPCORK option ...
