  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/amdkfd: Avoid integer underflow with ffs in EOP ring size calc  The low 6 bits of cp_hqd_eop_control store the base-2 logarithm of the EOP ring size. This was calculated as  ffs(q-\u003eeop_ring_buffer_size / sizeof(unsigned int)) - 1 - 1  But ffs can in theory return 1 or 0, so this could underflow (although in practice the ring buffer size cannot be less than 4096).  Change this to  ffs(q-\u003eeop_ring_buffer_size / sizeof(unsigned int) / 4)  using properties of logarithms.  (cherry picked from commit 4f18c56630383c14bfc6b2d65f88f2f895d2121a)",
