CVE-2022-50492

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm: fix use-after-free on probe deferral<br /> <br /> The bridge counter was never reset when tearing down the DRM device so<br /> that stale pointers to deallocated structures would be accessed on the<br /> next tear down (e.g. after a second late bind deferral).<br /> <br /> Given enough bridges and a few probe deferrals this could currently also<br /> lead to data beyond the bridge array being corrupted.<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/502665/
