Title

hwmon: (gpio-fan) Fix array out of bounds access

Summary

In the Linux kernel, the following vulnerability has been resolved: hwmon: (gpio-fan) Fix array out of bounds access The driver does not check if the cooling state passed to gpio_fan_set_cur_state() exceeds the maximum cooling state as stored in fan_data->num_speeds. Since the cooling state is later used as an array index in set_fan_speed(), an array out of bounds access can occur. This can be exploited by setting the state of the thermal cooling device to arbitrary values, causing for example a kernel oops when unavailable memory is accessed this way. Example kernel oops: [ 807.987276] Unable to handle kernel paging request at virtual address ffffff80d0588064 [ 807.987369] Mem abort info: [ 807.987398] ESR = 0x96000005 [ 807.987428] EC = 0x25: DABT (current EL), IL = 32 bits [ 807.987477] SET = 0, FnV = 0 [ 807.987507] EA = 0, S1PTW = 0 [ 807.987536] FSC = 0x05: level 1 translation fault [ 807.987570] Data abort info: [ 807.987763] ISV = 0, ISS = 0x00000005 [ 807.987801] CM = 0, WnR = 0 [ 807.987832] swapper pgtable: 4k pages, 39-bit VAs, pgdp=0000000001165000 [ 807.987872] [ffffff80d0588064] pgd=0000000000000000, p4d=0000000000000000, pud=0000000000000000 [ 807.987961] Internal error: Oops: 96000005 [#1] PREEMPT SMP [ 807.987992] Modules linked in: cmac algif_hash aes_arm64 algif_skcipher af_alg bnep hci_uart btbcm bluetooth ecdh_generic ecc 8021q garp stp llc snd_soc_hdmi_codec brcmfmac vc4 brcmutil cec drm_kms_helper snd_soc_core cfg80211 snd_compress bcm2835_codec(C) snd_pcm_dmaengine syscopyarea bcm2835_isp(C) bcm2835_v4l2(C) sysfillrect v4l2_mem2mem bcm2835_mmal_vchiq(C) raspberrypi_hwmon sysimgblt videobuf2_dma_contig videobuf2_vmalloc fb_sys_fops videobuf2_memops rfkill videobuf2_v4l2 videobuf2_common i2c_bcm2835 snd_bcm2835(C) videodev snd_pcm snd_timer snd mc vc_sm_cma(C) gpio_fan uio_pdrv_genirq uio drm fuse drm_panel_orientation_quirks backlight ip_tables x_tables ipv6 [ 807.988508] CPU: 0 PID: 1321 Comm: bash Tainted: G C 5.15.56-v8+ #1575 [ 807.988548] Hardware name: Raspberry Pi 3 Model B Rev 1.2 (DT) [ 807.988574] pstate: 20000005 (nzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 807.988608] pc : set_fan_speed.part.5+0x34/0x80 [gpio_fan] [ 807.988654] lr : gpio_fan_set_cur_state+0x34/0x50 [gpio_fan] [ 807.988691] sp : ffffffc008cf3bd0 [ 807.988710] x29: ffffffc008cf3bd0 x28: ffffff80019edac0 x27: 0000000000000000 [ 807.988762] x26: 0000000000000000 x25: 0000000000000000 x24: ffffff800747c920 [ 807.988787] x23: 000000000000000a x22: ffffff800369f000 x21: 000000001999997c [ 807.988854] x20: ffffff800369f2e8 x19: ffffff8002ae8080 x18: 0000000000000000 [ 807.988877] x17: 0000000000000000 x16: 0000000000000000 x15: 000000559e271b70 [ 807.988938] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000 [ 807.988960] x11: 0000000000000000 x10: ffffffc008cf3c20 x9 : ffffffcfb60c741c [ 807.989018] x8 : 000000000000000a x7 : 00000000ffffffc9 x6 : 0000000000000009 [ 807.989040] x5 : 000000000000002a x4 : 0000000000000000 x3 : ffffff800369f2e8 [ 807.989062] x2 : 000000000000e780 x1 : 0000000000000001 x0 : ffffff80d0588060 [ 807.989084] Call trace: [ 807.989091] set_fan_speed.part.5+0x34/0x80 [gpio_fan] [ 807.989113] gpio_fan_set_cur_state+0x34/0x50 [gpio_fan] [ 807.989199] cur_state_store+0x84/0xd0 [ 807.989221] dev_attr_store+0x20/0x38 [ 807.989262] sysfs_kf_write+0x4c/0x60 [ 807.989282] kernfs_fop_write_iter+0x130/0x1c0 [ 807.989298] new_sync_write+0x10c/0x190 [ 807.989315] vfs_write+0x254/0x378 [ 807.989362] ksys_write+0x70/0xf8 [ 807.989379] __arm64_sys_write+0x24/0x30 [ 807.989424] invoke_syscall+0x4c/0x110 [ 807.989442] el0_svc_common.constprop.3+0xfc/0x120 [ 807.989458] do_el0_svc+0x2c/0x90 [ 807.989473] el0_svc+0x24/0x60 [ 807.989544] el0t_64_sync_handler+0x90/0xb8 [ 807.989558] el0t_64_sync+0x1a0/0x1a4 [ 807.989579] Code: b9403801 f9402800 7100003f 8b35cc00 (b9400416) [ 807.989627] ---[ end t ---truncated---

Detection rules are retrieved from Rulezet.

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.
