Technical details
An out-of-bounds read vulnerability exists in rb_cpu_init within the KVM trace subsystem (arch/arm64/kvm/hyp/nvhe/trace.c) caused by an incorrect bounds check. The vulnerability occurs when an error happens during cpu_buffer initialization; if nr_pages does not accurately reflect the number of allocated pages, the teardown path may access memory beyond the allocated region. A local attacker with no special privileges can exploit this to leak kernel memory.
