{"id":"CVE-2026-80604","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-80604","summary":"HID: core: Fix OOB read in hid_get_report for numbered reports","details":"In the Linux kernel, the following vulnerability 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.","published":"2026-08-28T06:48:29.755Z","modified":"2026-08-30T03:48:23.070584950Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.261"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/30ff978af92cb51c9ba99f96fc4f4ac80d7001ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/af1a9b65ebe8a948eda805c14b78d4d0767cb1b5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c1fc0d3aff26ec9ff885b3e4c92eba98cf349678"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c39f5765ad840b71ff8db812d0210f216cca96e4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c973d53bcd420b58c4a34c68198746286d77e9fa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd395744e4ed87956fcbf81ecc6a20c51e35fa4e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7e8117e42b20c30d2a5edab82c944a5e381d791"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f8896b684e246f3f00f45ba2b6803ae59b9cc768"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80604.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80604"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-30T03:48:23.070584950Z"}}
