CVE-2023-53703
Estado: AplazadaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
HID: amd_sfh: Fix for shift-out-of-bounds
Shift operation of 'exp' and 'shift' variables exceeds the maximum number of shift values in the u32 range leading to UBSAN shift-out-of-bounds.
Fix this by adding the condition to validate shift ranges.
