CVE-2024-50274
7.8 · HIGHOverview
CVE-2024-50274 is a high-severity vulnerability affecting linux linux_kernel. It was published on November 19, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
idpf: avoid vport access in idpf_get_link_ksettings
When the device control plane is removed or the platform
running device control plane is rebooted, a reset is detected
on the driver. On driver reset, it releases the resources and
waits for the reset to complete. If the reset fails, it takes
the error path and releases the vport lock. At this time if the
monitoring tools tries to access link settings, it call traces
for accessing released vport pointer.
To avoid it, move link_speed_mbps to netdev_priv structure
which removes the dependency on vport pointer and the vport lock
in idpf_get_link_ksettings. Also use netif_carrier_ok()
to check the link status and adjust the offsetof to use link_up
instead of link_speed_mbps.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
