Summary

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Fix kvzalloc vs state_kcalloc usage adreno_show_object() is a trap! It will re-allocate the pointer it is passed on first call, when the data is ascii85 encoded, using kvmalloc/ kvfree(). Which means the data *passed* to it must be kvmalloc'd, ie. we cannot use the state_kcalloc() helper. This partially reverts commit ec8f1813bf8d ("drm/msm/a6xx: Replace kcalloc() with kvzalloc()"), but adds the missing kvfree() to fix the memory leak that was present previously. And adds a warning comment. Patchwork: https://patchwork.freedesktop.org/patch/507014/
