  "details": "In the Linux kernel, the following vulnerability has been resolved:  KVM: arm64: Fix AArch32 DBGBXVR\u003cn\u003e handling  The consolidation of the breakpoint and watchpoint register accessors switched DBGBXVR\u003cn\u003e from trap_bvr() to trap_dbg_wb_reg(). The latter selects backing storage with demux_wb_reg(), which only handles Op2 values 4 through 7. Since DBGBXVR\u003cn\u003e uses Op2 1, an AArch32 guest access hits KVM_BUG_ON() and marks the VM dead.  DBGBXVR\u003cn\u003e aliases DBGBVR\u003cn\u003e_EL1[63:32], and its AA32(HI) descriptor already selects the upper half. Map Op2 1 to dbg_bvr[] alongside Op2 4, restoring the pre-regression behavior.",
