CVE-2026-65200

The openUBMC device-management process parses PLDM-over-MCTP and NCSI-over-MCTP responses from on-bus devices, and three response parsers in the shared transport libraries subtract a fixed header or reserved-field size from a device-supplied response length without a lower-bound check. An...

CVE-2026-65200 Huawei malicious on-bus PLDM or NCSI device can drive out-of-bounds-heap reads via short MCTP responses

The openUBMC device-management process parses PLDM-over-MCTP and NCSI-over-MCTP responses from on-bus devices, and three response parsers in the shared transport libraries subtract a fixed header or reserved-field size from a device-supplied response length without a lower-bound check. An...

CVE-2026-65200

The openUBMC device-management process is vulnerable to an out-of-bounds heap read due to an integer underflow. Three response parsers within the shared transport libraries fail to perform a lower-bound check when subtracting a fixed header or reserved-field size from a device-supplied response l...

ROS-20261012-73-0060

The vulnerability of the mctpflowprepareoutput function in the net/mctp/route.c module of the Linux kernel is related to deficiencies in the deserialization mechanism, due to insufficient protection of sensitive data. Exploiting this vulnerability allows an attacker to compromise the...

ROS-20261012-73-0234

The vulnerability of the mctp-i2c.c component in the Linux operating system’s kernel is related to the use of an uninitialized resource. Exploiting this vulnerability could allow an attacker to access confidential data...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mctp: Serial: Handling of zero-length frames to prevent RX buffer overflow The MCTP serial receive state machine reads the frame length byte in the mctpSerialPushHeader function’s case 2, and validates it as an upper-bound-only...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mctp: Fixed an error handling path in mctpinit. If mctpneighinit returns an error, the route resources should be released during the error handling path. Otherwise, some resources may be leaked...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: mctp: Do not access ifaindex when it is missing In mctpdumpaddrinfo, ifaindex can be used to filter interfaces, but only when the struct ifaddrmsg is provided. Otherwise, it will compare to uninitialized memory—a...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: Initializing the event handler for read bytes A value of 0xff was set for I2C reads of the mctp-i2c device. Otherwise, reads will return “val” from the I2C bus driver. For I2c-aspeed and i2c-npcm7xx, this represents an...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mctp: Route lookups now perform under a RCU read-side lock. Our current route lookups mctproutelookup and mctproutelookupnull traverse the network’s route list without holding the RCU read lock. This means that the route lookups...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: - mctp i2c: Handle the NULL header address. - daddr can be NULL if there is no neighbour table entry present; in that case, the TX packet should be discarded. - saddr is usually set by the MCTP core, but check for NULL in case...

CVE-2026-98018

A flaw was found in the Linux kernel. A race condition in the Management Component Transport Protocol MCTP I3C driver occurs when device discovery releases a lock prematurely while a bus is simultaneously removed. A local user could exploit this synchronization flaw to access freed memory,...

DEBIAN-CVE-2026-98018

In the Linux kernel, the following vulnerability has been resolved: net: mctp: i3c: serialize probe with bus removal mctpi3cprobe drops busdevslock after finding the matching bus. A concurrent I3CNOTIFYBUSREMOVE can then unregister and free the bus netdev before probe passes its private data to...

CVE-2026-98018

A vulnerability exists in the Linux kernel within the net: mctp: i3c component. The root cause is that mctp_i3c_probe() drops the busdevs_lock prematurely after finding the matching bus. This allows a concurrent I3C_NOTIFY_BUS_REMOVE event to unregister and free the bus netdev before the probe ca...
