Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2026-98188)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 0 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause out-of-bounds reads past the EEPROM buffer.
The vulnerability exists due to an out-of-bounds read in p54_convert_rev0() and p54_convert_rev1() when processing device-supplied EEPROM calibration curve entries with channel and points-per-channel counts that exceed the available entry data. A local user can supply an EEPROM entry declaring more calibration curve data than it contains to cause out-of-bounds reads past the EEPROM buffer.
Exploitation requires control over the device-supplied EEPROM entry.
Remediation
Install update from vendor's website.
