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

In the Linux kernel, the following vulnerabilities have been resolved: llc: A test for maclen should be performed before reading the MAC header. The LLC layer reads the MAC header using ethhdr, without verifying that the skb contains an Ethernet header. Syzbot was able to access the llcrcv functi...

SUSE CVE-2023-52843

In the Linux kernel, the following vulnerability has been resolved: llc: verify mac len before reading mac header LLC reads the mac header with ethhdr without verifying that the skb has an Ethernet header. Syzbot was able to enter llcrcv on a tun device. Tun can insert packets without mac len and...

CVE-2023-52843

CVE-2023-52843 (Linux kernel): The vulnerability arises in LLC processing where mac headers are read via eth_hdr without verifying that skb contains an Ethernet header. Syzbot demonstrated entry into llc_rcv on a tun device, with tun injections that can bypass mac_len validation. The fix adds a m...

The vulnerability of the llc_conn_handler() function in the net/llc/llc_conn.c module, which is part of the LLC protocol implementation in Linux kernel, allows a attacker to cause a service failure.

The vulnerability of the llcconnhandler function in the net/llc/llcconn.c module, which is part of the LLC protocol implementation in Linux kernel, is related to the use of uninitialized memory. Exploiting this vulnerability could allow an attacker to cause a service failure...
