Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the netdevsim component where the
struct iphdr in a dummy sk buff is not properly initialized. This leads to a KMSAN uninit-value, which occurs when the kernel accesses memory that has been allocated but not initialized. The problem originates from the nsim dev trap skb build() function, where the allocation and the subsequent use of the uninitialized value occur.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Exploit
Access of Uninitialized Pointer
Use of Uninitialized Resource
