  "message": "perf/core: Exit early on perf_mmap() fail\n\ncommit 07091aade394f690e7b655578140ef84d0e8d7b0 upstream.\n\nWhen perf_mmap() fails to allocate a buffer, it still invokes the\nevent_mapped() callback of the related event. On X86 this might increase\nthe perf_rdpmc_allowed reference counter. But nothing undoes this as\nperf_mmap_close() is never called in this case, which causes another\nreference count leak.\n\nReturn early on failure to prevent that.\n\nBUG\u003db/440033877\nTEST\u003dpresubmit\nRELEASE_NOTE\u003dFixed CVE-2025-38565 in the Linux kernel.\n\ncos-patch: security-moderate\nFixes: 1e0fb9ec679c (\"perf/core: Add pmu callbacks to track event mapping and unmapping\")\nChange-Id: I1c2d09a923559b9dcc3a24c2775cd434dd4bb9ca\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReviewed-by: Lorenzo Stoakes \u003clorenzo.stoakes@oracle.com\u003eCc: stable@vger.kernel.org\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nSigned-off-by: Robert Kolchmeyer \u003crkolchmeyer@google.com\u003e\nReviewed-on: https://cos-review.googlesource.com/c/third_party/kernel/+/111039\nReviewed-by: Chenglong Tang \u003cchenglongtang@google.com\u003e\nTested-by: Cusky Presubmit Bot \u003cpresubmit@cos-infra-prod.iam.gserviceaccount.com\u003e\n",
