In FRRouting (FRR) through 9.1, it is possible for the get_edge() function in ospf_te.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value, the OSPF daemon crashes, leading to denial of service.

CVE-2024-31950 FRR vulnerabilities
Title: FRR vulnerabilities
Summary: Several security issues were fixed in FRR.
It was discovered that FRR incorrectly handled certain malformed BGP and
OSPF packets. A remote attacker could use this issue to cause FRR to crash,
resulting in a denial of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2024-34088 [HIGH] CWE-476 frr: null pointer via get_edge() function can trigger a denial of service
frr: null pointer via get_edge() function can trigger a denial of service
In FRRouting (FRR) through 9.1, it is possible for the get_edge() function in ospf_te.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value, the OSPF daemon crashes, leading to denial of service.
A flaw was found in FRRouting (FRR). Some functions do not check the return value of the get_edge function in the ospfd/ospf_te.c file, allowing a NULL pointer dereference, causing a crash in the OSPF daemon, resulting in a denial of service.
Statement: The get_edge function can return a NULL pointer when processing specially crafted link IDs or advertised router IP addresses. When the NULL pointer is returned from the get_edge function and this return value

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact
