| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the
anysee master xfer function related to a null pointer dereference. The msg variable, controlled by the user, lacks proper validation. Specifically, if msg[i].buf is null and msg[i].len is zero, checks on msg[i].buf may be bypassed, allowing malicious data to reach anysee master xfer. Subsequently, accessing msg[i].buf[0] without a sanity check can lead to a null pointer dereference. The issue is addressed by adding a check on msg[i].len to prevent a crash.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
