Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the Linux kernel, specifically the mctp i2c component. It involves handling a NULL header address. The daddr can be NULL if there is no entry present in the neighbour table, in which case the tx packet should be dropped. The saddr is usually set by the MCTP core but checks for NULL in case a packet is transmitted by a different protocol.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
