Summary
dma-mapping: benchmark: fix node id validation
Details

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

dma-mapping: benchmark: fix node id validation

While validating node ids in mapbenchmarkioctl(), nodepossible() may be provided with invalid argument outside of [0,MAXNUMNODES-1] range leading to:

BUG: KASAN: wild-memory-access in mapbenchmarkioctl (kernel/dma/mapbenchmark.c:214) Read of size 8 at addr 1fffffff8ccb6398 by task dmamapbenchma/971 CPU: 7 PID: 971 Comm: dmamapbenchma Not tainted 6.9.0-rc6 #37 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) Call Trace: <TASK> dumpstacklvl (lib/dumpstack.c:117) kasanreport (mm/kasan/report.c:603) kasancheckrange (mm/kasan/generic.c:189) variabletestbit (arch/x86/include/asm/bitops.h:227) [inline] archtestbit (arch/x86/include/asm/bitops.h:239) [inline] _testbit at (include/asm-generic/bitops/instrumented-non-atomic.h:142) [inline] nodestate (include/linux/nodemask.h:423) [inline] mapbenchmarkioctl (kernel/dma/mapbenchmark.c:214) fullproxyunlockedioctl (fs/debugfs/file.c:333) _x64sysioctl (fs/ioctl.c:890) dosyscall64 (arch/x86/entry/common.c:83) entrySYSCALL64afterhwframe (arch/x86/entry/entry_64.S:130)

Compare node ids with sane bounds first. NUMANONODE is considered a special valid case meaning that benchmarking kthreads won't be bound to a cpuset of a given node.
