Vulnerability from fkie_nvd - Published: 2026-08-28 08:16 - Updated: 2026-08-29 07:16
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: core: Fix OOB read in hid_get_report for numbered reports
When a caller passes a size of 0 to hid_report_raw_event() for a
numbered report, the function originally called hid_get_report() before
performing any size validation.
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.
