| Vector | AV:L/AC:H/Au:S/C:C/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 Open vSwitch component related to insufficient validation of attributes in the
push nsh() action. Specifically, the code does not adequately verify the size or type of an intermediate attribute during nested attribute processing. This can lead to an invalid memory access, potentially causing a kernel crash. The issue arises from a double unwrap of attributes without proper size checking, which can trigger a slab-out-of-bounds error during action execution. The vulnerability is triggered when processing NSH headers and may occur during action execution due to an incorrectly sized netlink buffer.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
