In the Linux kernel, the following vulnerability has been resolved:
thermal/core: Fix memory leak in _thermalcoolingdeviceregister()
I got memory leak as follows when doing fault injection test:
unreferenced object 0xffff888010080000 (size 264312): comm "182", pid 102533, jiffies 4296434960 (age 10.100s) hex dump (first 32 bytes): 00 00 00 00 ad 4e ad de ff ff ff ff 00 00 00 00 .....N.......... ff ff ff ff ff ff ff ff 40 7f 1f b9 ff ff ff ff ........@....... backtrace: [<0000000038b2f4fc>] kmallocordertrace+0x1d/0x110 mm/slabcommon.c:969 [<00000000ebcb8da5>] _kmalloc+0x373/0x420 include/linux/slab.h:510 [<0000000084137f13>] thermalcoolingdevicesetupsysfs+0x15d/0x2d0 include/linux/slab.h:586 [<00000000352b8755>] _thermalcoolingdeviceregister+0x332/0xa60 drivers/thermal/thermalcore.c:927 [<00000000fb9f331b>] devmthermalofcoolingdeviceregister+0x6b/0xf0 drivers/thermal/thermalcore.c:1041 [<000000009b8012d2>] max6650probe.cold+0x557/0x6aa drivers/hwmon/max6650.c:211 [<00000000da0b7e04>] i2cdeviceprobe+0x472/0xac0 drivers/i2c/i2c-core-base.c:561
If deviceregister() fails, thermalcoolingdevicedestroysysfs() need be called to free the memory allocated in thermalcoolingdevicesetup_sysfs().
