The product reads data past the end, or before the beginning, of the intended buffer. Impacted is availability. CVE summarizes:

An issue was discovered in bgpd in FRRouting (FRR) through 8.4. By crafting a BGP OPEN message with an option of type 0xff (Extended Length from RFC 9072), attackers may cause a denial of service (assertion failure and daemon restart, or out-of-bounds read). This is possible because of inconsistent boundary checks that do not account for reading 3 bytes (instead of 2) in this 0xff case. NOTE: this behavior occurs in bgp_open_option_parse in the bgp_open.c file, a different location (with a different attack vector) relative to CVE-2022-40302.

The weakness was presented 05/03/2023. This vulnerability is handled as CVE-2022-40318 since 09/09/2022. Technical details are known, but there is no available exploit.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
