Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a heap out-of-bounds condition in AF PACKET sockets, similar to a previously disclosed problem. It involves a race condition between a socket option that changes socket state and safety checks in
packet set ring, specifically with PACKET RESERVE. This could potentially be exploitable, although further investigation was not conducted. The issue affects PF PACKET sockets and requires the CAP NET RAW capability in the process namespace. However, with user namespaces enabled, any process can create a namespace where it has CAP NET RAW, potentially increasing the exploitability.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
