CVE-2022-50360

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm/dp: fix aux-bus EP lifetime<br /> <br /> Device-managed resources allocated post component bind must be tied to<br /> the lifetime of the aggregate DRM device or they will not necessarily be<br /> released when binding of the aggregate device is deferred.<br /> <br /> This can lead resource leaks or failure to bind the aggregate device<br /> when binding is later retried and a second attempt to allocate the<br /> resources is made.<br /> <br /> For the DP aux-bus, an attempt to populate the bus a second time will<br /> simply fail ("DP AUX EP device already populated").<br /> <br /> Fix this by tying the lifetime of the EP device to the DRM device rather<br /> than DP controller platform device.<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/502672/
