| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the dpaa2-switch driver where a zero-sized pointer dereference can occur when the number of interfaces (
num ifs) reported by the device is zero. This happens because kcalloc() returns a zero-sized pointer (0x10) when the element count is zero, and subsequent code attempts to access memory at this invalid address, leading to a kernel panic. The issue arises from unconditionally accessing ethsw->ports[0]->netdev without verifying that num ifs is greater than zero after retrieving device attributes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
