SB20260928400 - Type Confusion in Linux kernel scsi qla2xxx driver

Description

This security bulletin contains information about 1 vulnerability.

1) Type Confusion (CVE-ID: CVE-2026-97530)

CWE-ID: CWE-843 - Type confusion

CVSSv4: 7.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper interpretation of continuation IOCB payload data in the qla2xxx driver's qla27xx_copy_multiple_pkt() and qla27xx_copy_fpin_pkt() functions when processing a crafted Fibre Channel frame. A remote attacker can send a frame with payload bytes matching the RESPONSE_PROCESSED value to cause a denial of service.

The affected processing occurs in interrupt/DPC context.
