  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/amdkfd: Avoid integer underflow in EOP ring size calculation.  The low 6 bits of cp_hqd_eop_control store the base-2 logarithm of the EOP ring size. This was calculated as  order_base_2(q-\u003eeop_ring_buffer_size / 4) - 1  But order_base_2 can in theory return 0, so this could underflow (although in practice the ring buffer size cannot be less than 4096).  Change this to  order_base_2(q-\u003eeop_ring_buffer_size / 8)  using properties of logarithms.  Also add to the above comment to make the mathematics more clear.  (cherry picked from commit f0f43fcf8b2b3a924cad9444340921c96ed5f634)",
