Details

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

thermal/core: Fix memory leak in __thermal_cooling_device_register()

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>] kmalloc_order_trace+0x1d/0x110 mm/slab_common.c:969 [<00000000ebcb8da5>] __kmalloc+0x373/0x420 include/linux/slab.h:510 [<0000000084137f13>] thermal_cooling_device_setup_sysfs+0x15d/0x2d0 include/linux/slab.h:586 [<00000000352b8755>] __thermal_cooling_device_register+0x332/0xa60 drivers/thermal/thermal_core.c:927 [<00000000fb9f331b>] devm_thermal_of_cooling_device_register+0x6b/0xf0 drivers/thermal/thermal_core.c:1041 [<000000009b8012d2>] max6650_probe.cold+0x557/0x6aa drivers/hwmon/max6650.c:211 [<00000000da0b7e04>] i2c_device_probe+0x472/0xac0 drivers/i2c/i2c-core-base.c:561

If device_register() fails, thermal_cooling_device_destroy_sysfs() need be called to free the memory allocated in thermal_cooling_device_setup_sysfs().

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
