Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s AFS subsystem where a null pointer dereference could occur within the
afs put server() function. Specifically, the function accessed server->debug id before verifying that the server pointer was not NULL. This could lead to a system crash or other undefined behavior. The issue was addressed by moving the assignment of debug id, ensuring a NULL server pointer is never dereferenced.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
