Inside hid_get_report(), if the report is numbered (report_enum->numbered is true), it unconditionally dereferences data[0] to extract the report ID. With a size of 0, this results in an out-of-bounds read or kernel panic. Fix this by moving the numbered report size validation check before the call to hid_get_report(), ensuring that size is at least 1 before dereferencing the data pointer. The Linux kernel CVE team has assigned CVE-2026-80604 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/hid/hid-core.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/f8896b684e246f3f00f45ba2b6803ae59b9cc768 https://git.kernel.org/stable/c/30ff978af92cb51c9ba99f96fc4f4ac80d7001ba https://git.kernel.org/stable/c/c39f5765ad840b71ff8db812d0210f216cca96e4 https://git.kernel.org/stable/c/c973d53bcd420b58c4a34c68198746286d77e9fa https://git.kernel.org/stable/c/c1fc0d3aff26ec9ff885b3e4c92eba98cf349678 https://git.kernel.org/stable/c/dd395744e4ed87956fcbf81ecc6a20c51e35fa4e https://git.kernel.org/stable/c/f7e8117e42b20c30d2a5edab82c944a5e381d791 https://git.kernel.org/stable/c/af1a9b65ebe8a948eda805c14b78d4d0767cb1b5
