resolved:\nperf/core: Check kernel access when kernel callchains are requested\nperf_event_open() currently gates perf_allow_kernel() only on!attr.exclude_kernel.\nHowever, users can still request kernel callchain collection withattr.exclude_callchain_kernel == 0 even when attr.exclude_kernel == 1.That still requires kernel profiling privilege, but the existing checkdoes not enforce it.\nUpdate the permission check to call perf_allow_kernel() when eitherkernel sampling is requested or kernel callchains are requested.\nThis keeps permission checks aligned with requested data and preventsunprivileged use of kernel callchain capture.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98937https://git.kernel.org/stable/c/132bee76097be421ab3012130b5b506324cf2be1https://git.kernel.org/stable/c/2581b43e162cfc43e6f5d8dd8d2b38f3441550dehttps://git.kernel.org/stable/c/6e187281f978a2bff98ead6aa40f8ddc9a2c9afbhttps://git.kernel.org/stable/c/a4573a3838ae4fc73b70019cfa1dac9aaea7cc2f#kernel
