has been resolved:\n\nHID: core: Fix OOB read in hid_get_report for numbered reports\n\nWhen a caller passes a size of 0 to hid_report_raw_event() for a\nnumbered report, the function originally called hid_get_report() before\nperforming any size validation.\n\nInside hid_get_report(), if the report is numbered (report_enum->numbered\nis true), it unconditionally dereferences data[0] to extract the report ID.\nWith a size of 0, this results in an out-of-bounds read or kernel panic.\n\nFix this by moving the numbered report size validation check before the\ncall to hid_get_report(), ensuring that size is at least 1 before\ndereferencing the data pointer." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:A - A malicious Bluetooth HID peripheral with numbered reports can reach hid_report_raw_event() during driver probe/feature mapping (e.g., mt_get_feature()) when hid_report_len() is 0, bypassing __hid_input_report(); BT HIDP delivers attacker-controlled descriptors over an adjacent wireless link.\nAC:L - An attacker fully controls the HID report descriptor and GET_REPORT responses; pairing/connecting a device with numbered reports plus a zero-length report ID 0 deterministically calls hid_report_raw_event() with size 0 during probe, with no race or victim-specific heap layout required.\nPR:N - Exploitation requires only a malicious HID peripheral presenting a crafted numbered-report descriptor; the attacker needs no local account, capabilities, or init-namespace privileges on the victim host.\nUI:N - Feature-mapping probe I/O runs automatically during HID enumeration when the device connects or auto-reconnects; no additional victim file-open, mount, or application interaction is needed beyond standard peripheral attachment handled by the kernel.\nS:U - The out-of-bounds read and kernel panic occur entirely within host kernel HID-core processing; impact does not cross a VM, container, or IOMMU boundary to a separate security authority.\nC:H - On numbered-report devices, hid_get_report() dereferences data[0] before any size validation when size is 0, causing an out-of-bounds kernel memory read that may disclose adjacent heap or slab contents.\nI:H - Kernel heap out-of-bounds reads in HID-core can corrupt parser state or be chained with further memory corruption primitives; per kernel guidance, OOB reads in kernel context warrant High integrity impact when exploitation potential exists.\nA:H - The fix commit and CVE description state that dereferencing data[0] with size 0 on numbered reports can cause a kernel panic; this is a kernel oops-class failure denying system availability until reboot." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
