Description

This security bulletin contains information about 1 vulnerability.


1) Off-by-one (CVE-ID: CVE-2026-98675)

CWE-ID: CWE-193 - Off-by-one Error

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to prevent Phase C dip events from being reported.

The vulnerability exists due to an off-by-one error in the Linux kernel ADE9000 ADC driver's IRQ1 handler when scanning STATUS1 event bits. A local user can take advantage of the scan excluding bit 25, ADE9000_ST1_DIPC_BIT, to leave Phase C dip events unreported.
