{"schema":"threatline.record/2","record":{"id":"CVE-2026-98860","aliases":[],"summary":"HID: bpf: cast size to ssize_t when checking hid_bpf_hw_request","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: bpf: cast size to ssize_t when checking hid_bpf_hw_request\n\nAs reported by Sashiko:\nIf a transport driver encounters a hardware error and returns a negative\nerror code such as -EPIPE, ret is implicitly promoted to size_t when\ncompared against size. This causes the negative error code to evaluate\nas a large positive number, making the (ret > size) condition true.\n\nThis silently converts the hardware error into a success return value\nand copies the unmodified buffer back, which could leave BPF programs\noperating on uninitialized or stale data.\n\nFix this by casting size into ssize_t to return the actual negative\nerror code.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
