CVSS: 7.8EPSS: 0%CPEs: -EXPL: 0CVE-2024-9050 – Networkmanager-libreswan: local privilege escalation via leftupdown
https://notcve.org/view.php?id=CVE-2024-9050
A flaw was found in the libreswan client plugin for NetworkManager (NetkworkManager-libreswan), where it fails to properly sanitize the VPN configuration from the local unprivileged user. In this configuration, composed by a key-value format, the plugin fails to escape special characters, leading the application to interpret values as keys. One of the most critical parameters that could be abused by a malicious user is the `leftupdown`key. This key takes an executable command as a value and is used to specify what executes as a callback in NetworkManager-libreswan to retrieve configuration settings back to NetworkManager. As NetworkManager uses Polkit to allow an unprivileged user to control the system's network configuration, a malicious actor could achieve local privilege escalation and potential code execution as root in the targeted machine by creating a malicious configuration. • https://access.redhat.com/errata/RHSA-2024:8312 https://access.redhat.com/errata/RHSA-2024:8338 https://access.redhat.com/errata/RHSA-2024:8352 https://access.redhat.com/errata/RHSA-2024:8353 https://access.redhat.com/errata/RHSA-2024:8354 https://access.redhat.com/errata/RHSA-2024:8355 https://access.redhat.com/errata/RHSA-2024:8356 https://access.redhat.com/errata/RHSA-2024:8357 https://access.redhat.com/errata/RHSA-2024:8358 https://access.redhat.com/errata/RHSA • CWE-94: Improper Control of Generation of Code ('Code Injection') •

CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-49863 – vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()
https://notcve.org/view.php?id=CVE-2024-49863
In the Linux kernel, the following vulnerability has been resolved: vhost/scsi: null-ptr-dereference in vhost_scsi_get_req() Since commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling code from control queue handler") a null pointer dereference bug can be triggered when guest sends an SCSI AN request. In vhost_scsi_ctl_handle_vq(), `vc.target` is assigned with `&v_req.tmf.lun[1]` within a switch-case block and is then passed to vhost_scsi_get_req() which extracts `vc->req` and `tpg`. However, for a `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` is set to NULL in this branch. Later, in vhost_scsi_get_req(), `vc->target` is dereferenced without being checked, leading to a null pointer dereference bug. This bug can be triggered from guest. When this bug occurs, the vhost_worker process is killed while holding `vq->mutex` and the corresponding tpg will remain occupied indefinitely.
