GHSA-7235-89M6-F4PX
Vulnerability from github – Published: 2026-04-29 20:43 – Updated: 2026-05-08 20:42Summary
A remote Denial of Service (DoS) vulnerability exists in GoBGP due to a nil pointer dereference. When a malformed BGP UPDATE message contains an unrecognized Path Attribute marked as "Well-known," the daemon fails to interrupt the message handling flow. This results in an illegal memory access and a full process crash (panic).
Details
The vulnerability is located in the Finite State Machine (FSM) message handling loop in pkg/server/fsm.go. According to RFC 4271, any Path Attribute with the Optional bit set to 0 is treated as "Well-known." If the Type Code is unrecognized, the BGP speaker MUST send a NOTIFICATION message.
In GoBGP v4.3.0, when such an attribute (e.g., Type 0xEE or 0xFF with flags 0x40) is received, the parsing layer identifies the error. However, the logic in recvMessageloop (around Line 1826) does not properly halt execution. It proceeds to reference the body of the parsed message. Because the message was deemed invalid during the initial attribute check, the body pointer is nil, leading to: panic: runtime error: invalid memory address or nil pointer dereference.
This bypasses the intended error-handling mechanism and causes the entire BGP daemon to terminate, rather than just closing the affected session.

GoBGP Version: v4.3.0 Configure GoBGP with a neighbor (e.g., 192.168.31.195) in passive mode. Establish a standard BGP session (OPEN/KEEPALIVE exchange). Send a specifically crafted UPDATE packet containing an unrecognized Type Code marked as "Well-known" (Optional bit = 0). Payload 1 (Hex):
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

00 04 # Total Path Attribute Length: 4

40 FF 00 # Flag: 0x40 (Well-known, Transitive), Type: 0xFF (Unknown), Len: 0
Impact
This vulnerability affects all GoBGP deployments peering with external or internal speakers. A single malformed UPDATE message from any peer can trigger a nil pointer dereference, causing the GoBGP daemon to panic and crash.

GHSA-726G-XGHF-35VC
Vulnerability from github – Published: 2025-05-02 18:31 – Updated: 2025-11-10 18:30In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add()
Port is allocated by sas_port_alloc_num() and rphy is allocated by either sas_end_device_alloc() or sas_expander_alloc(), all of which may return NULL. So we need to check the rphy to avoid possible NULL pointer access.
If sas_rphy_add() returned with failure, rphy is set to NULL. We would access the rphy in the following lines which would also result NULL pointer access.

GHSA-72V6-VMR5-V9QF
Vulnerability from github – Published: 2024-07-16 12:30 – Updated: 2024-08-21 18:31In the Linux kernel, the following vulnerability has been resolved:
mtd: parsers: qcom: Fix kernel panic on skipped partition
In the event of a skipped partition (case when the entry name is empty) the kernel panics in the cleanup function as the name entry is NULL. Rework the parser logic by first checking the real partition number and then allocate the space and set the data for the valid partitions.
The logic was also fundamentally wrong as with a skipped partition, the parts number returned was incorrect by not decreasing it for the skipped partitions.

Due to not check the specially XML file enough an authenticated local attacker may craft specific XML files to the affected products and parse this file which cause to null pointer accessing and result in DoS attacks.

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
