Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/i915: Fix a memory leak with reused mmap_offset<br />
<br />
drm_vma_node_allow() and drm_vma_node_revoke() should be called in<br />
balanced pairs. We call drm_vma_node_allow() once per-file everytime a<br />
user calls mmap_offset, but only call drm_vma_node_revoke once per-file<br />
on each mmap_offset. As the mmap_offset is reused by the client, the<br />
per-file vm_count may remain non-zero and the rbtree leaked.<br />
<br />
Call drm_vma_node_allow_once() instead to prevent that memory leak.
