CVE-2026-80570
7.8 · HIGHOverview
CVE-2026-80570 is a high-severity vulnerability. It was published on August 26, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
Input: synaptics-rmi4 - zero report size on F54 work error
In rmi_f54_work(), if an error occurs during report request or command
verification, the code jumped directly to the 'error' label, bypassing
the 'abort' label where f54->report_size was normally zeroed out.
This left f54->report_size containing its previous successful payload
size. If a user then altered the V4L2 format to a smaller size, and a
subsequent run failed, rmi_f54_buffer_queue() would copy the stale,
larger payload size into the shrunken V4L2 buffer, causing a heap
buffer overflow.
Fix this by merging the 'abort' and 'error' labels into a single 'out'
exit path, and ensuring that f54->report_size is always set to 0 on
failure by checking for error and zeroing the local report_size first.
