| Description | In the Linux kernel, the following vulnerability has been resolved: HID: bpf: Fix hid_bpf_get_data() range check hid_bpf_get_data() returns a pointer into the HID-BPF context data when the caller-provided offset and size fit inside ctx->allocated_size. The current check adds rdwr_buf_size and offset before comparing the result against ctx->allocated_size. Since both values are unsigned, a very large size can wrap the sum below ctx->allocated_size and make the helper return a pointer even though the requested range is not contained in the backing buffer. Use check_add_overflow() to reject wrapped range ends before comparing the requested range end against ctx->allocated_size. |
