kernel: can: raw: fix ro->uniq use-after-free in raw_rcv()

A flaw was found in the Linux kernel's Controller Area Network CAN raw socket implementation. A use-after-free vulnerability can occur due to a timing window during the unregistration of CAN receive filters, allowing a freed memory region to be accessed. This could lead to system instability or a...

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

The IPv6 implementation in the Linux kernel before version 6.3 has a maxsize threshold in the net/ipv6/route.c file that can be easily exceeded. This can lead to a denial of service condition, where the network becomes unreachable, resulting in errors when IPv6 packets are sent through a raw sock...
