The issue is related to the `llc cmsg rcv` function in the Linux kernel, which fails to initialize a certain data structure. This allows attackers to obtain sensitive information from kernel stack memory by reading a message.

The issue allows attackers to cause a denial of service, resulting in an infinite loop and crash. This can be triggered remotely through the network by sending certain malformed packets, specifically IP packets with rarely used packet options. The exposure is specific to certain EOS releases that use the affected EosKernel-3.4.

The issue allows local users to obtain sensitive information from kernel stack memory. This is due to the nr recvmsg function in net/netrom/af netrom.c not initializing a certain data structure, which can be exploited via a crafted recvmsg or recvfrom system call.

The issue allows local users to obtain sensitive information from kernel stack memory. This is due to the failure of the net/dcb/dcbnl.c module in the Linux kernel to initialize certain structures, which can be exploited via a crafted application.

The issue allows local users to obtain sensitive information from kernel stack memory. This is due to the `caif seqpkt recvmsg` function in `net/caif/caif socket.c` not initializing a certain length variable, which can be exploited via a crafted `recvmsg` or `recvfrom` system call. Multiple vulnerabilities in the Linux operating system package may lead to disruption of confidentiality, integrity, and availability of protected information, potentially exploitable by a local attacker.
