CVE-2026-72236

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

s390/perf_cpum_cf: Add missing array_index_nospec() to __hw_perf_event_init()

ev variable is userspace controlled via event->attr.config and used as an array index after bounds checking, but without speculation barriers.

Add the missing array_index_nospec() call to prevent speculative execution.
