Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/nouveau/disp: fix use-after-free in error handling of nouveau_connector_create<br /> <br /> We can&amp;#39;t simply free the connector after calling drm_connector_init on it.<br /> We need to clean up the drm side first.<br /> <br /> It might not fix all regressions from commit 2b5d1c29f6c4<br /> ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"),<br /> but at least it fixes a memory corruption in error handling related to<br /> that commit.
