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

perf/core: Fix perfoutputbegin parameter is incorrectly invoked in perfeventbpf_output

syzkaller reportes a KASAN issue with stack-out-of-bounds.

commit 267fb27352b6 ("perf: Reduce stack usage of perfoutputbegin()") use on-stack struct perfsampledata of the caller function.

However, perfeventbpfoutput uses incorrect parameter to convert small-sized data (struct perfbpfevent) into large-sized data (struct perfsampledata), which causes memory overwriting occurs in perfeventheaderinitid.
