CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the HID-BPF context data handling within the hid_bpf_get_data() function, where improper range checks can lead to out-of-bounds access. This flaw could potentially allow attackers to exploit the kernel's memory management, leading to data corruption or unauthorized access. Organizations using affected Linux systems should prioritize this issue to mitigate risks associated with kernel-level vulnerabilities.
Original NVD 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.
