Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel's MCTP implementation has been resolved. The issue occurs in the
mctp dump addrinfo function when ifa index is accessed without proper initialization, potentially leading to comparison with uninitialized memory. This can be reproduced using syzkaller or by running specific commands like "ip addr show" with busybox. Existing userspace programs that dump MCTP addresses are expected to pass a valid ifa index value.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
