  - In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix crash in auto_retire The
    retire logic uses the 2 lower bits of the pointer to the retire function to store flags. However, the
    auto_retire function is not guaranteed to be aligned to a multiple of 4, which causes crashes as we jump
    to the wrong address, for example like this: 2021-04-24T18:03:53.804300Z WARNING kernel: [ 516.876901]
