A flaw was found in the Linux kernel. It is possible to overflow a perf_event's read_size, causing an out-of-bounds write in perf_read_group(). The check meant to prevent such an overflow in perf_event_validate_size() does not account for groups of events with mixed read_format values. The flaw can be triggered with events created with PERF_FORMAT_GROUP or events added with PERF_FORMAT_GROUP after some preconditions. The bug was introduced around fa8c269353d5 ("perf/core: Invert perf_read_group() loops"). Fixes: a723968c0ed3 ("perf: Fix u16 overflows").
