Security Advisory 2021-02-02-1 - netifd and odhcp6c routing loop on IPv6 point to point links (CVE-2021-22161)

DESCRIPTION In case a link prefix route points to a point-to-point link it can trigger a routing loop if the destination IPv6 address belongs to the prefix and is not a local IPv6 address. If such a packet is received and not directed to a local IPv6 address it will be routed back to the...

The vulnerability of the HDLC_PPP module in the Linux operating system, related to insufficient validation of input data, allows attackers to trigger service failures.

The vulnerability of the HDLCPPP module in the Linux operating system is related to insufficient validation of input data. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
