  "description": "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\u0027d, ie. we cannot use the state_kcalloc() helper.  This partially reverts commit ec8f1813bf8d (\u0022drm/msm/a6xx: Replace kcalloc() with kvzalloc()\u0022), 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/",
