Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the Linux kernel where the return type of the
lcs start xmit() function does not match the expected return type in the struct net device ops. Specifically, ndo start xmit() expects a return type of netdev tx t, but lcs start xmit() returns an integer. This discrepancy can lead to control flow integrity (CFI) failures when using clang's kernel CFI feature (CONFIG CFI CLANG), potentially resulting in a kernel panic or thread termination. This issue was identified through warnings generated by clang during compilation.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
