Debian Linux Security Advisory 5505-1 - Matteo Memelli reported an out-of-bounds read flaw when parsing CDP addresses in lldpd, an implementation of the IEEE 802.1ab (LLDP) protocol. A remote attacker can take advantage of this flaw to cause a denial of service via a specially crafted CDP PDU packet.

An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.

A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling. This issue allows a malicious link to insert an arbitrary URI into a Keycloak error page. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise user details, allowing it to be changed or collected by an attacker.
