Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds write (CVE-ID: CVE-2026-89619)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause memory corruption.
The vulnerability exists due to an out-of-bounds write in the quickspi_get_report() function of the intel-quickspi HID component when copying a device-supplied GET_REPORT response into a caller-provided buffer. A local user can request an input or feature report through hidraw with a buffer smaller than the returned response to cause memory corruption.
