CVE-2024-1151
Kernel: stack overflow problem in open vswitch kernel module leading to dos
A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues.
Fixes and workarounds
Workaround
To mitigate this issue, prevent module openvswitch from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
