1) Use of Uninitialized Variable (CVE-ID: CVE-2026-89852)
CWE-ID: CWE-457 - Use of Uninitialized Variable
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to disclose sensitive information.
The vulnerability exists due to use of an uninitialized variable in qla2x00_get_firmware_state() when querying firmware state through sysfs during a mailbox command failure. A local user can read firmware state through the fw_state or mpi_fw_state sysfs handlers during such a failure to disclose sensitive information.
Remediation
Install update from vendor's website.
