SB20260727119 - Double free in Linux kernel media ipu7 driver

Description

This security bulletin contains information about 1 vulnerability.

1) Double free (CVE-ID: CVE-2026-64447)

CWE-ID: CWE-415 - Double Free

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a double free and use-after-free in ipu7_isys_init() and ipu7_psys_init() when handling device initialization error paths. A local user can trigger device initialization failures to cause a denial of service.

The issue occurs in the error paths after device teardown frees pdata, and also affects return-value handling through dereference of an already-freed adev pointer.

Remediation

Install update from vendor's website.
