  - In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/disp: fix use-after-free
    in error handling of nouveau_connector_create We can't simply free the connector after calling
    drm_connector_init on it. We need to clean up the drm side first. It might not fix all regressions from
    commit 2b5d1c29f6c4 (drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts), but at least
    it fixes a memory corruption in error handling related to that commit. (CVE-2023-53263)

Note that Nessus relies on the presence of the package as reported by the vendor.");
