The vulnerability of the mctp_flow_prepare_output() function in the net/mctp/route.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

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, resulting from insufficient protection of sensitive data. Exploiting this vulnerability allows an attacker to compromise the...

The vulnerability of the mctp_i2c_recv() function in the drivers/net/mctp/mctp-i2c.c module of the MCTP serial transport driver for the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the mctpi2crecv function in the drivers/net/mctp/mctp-i2c.c module of the MCTP serial transport driver for the Linux operating system is related to improper memory release memory leak. Exploiting this vulnerability may allow a remote attacker to cause service interruptions...

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...
