SB2026102447 - Out-of-bounds write in Linux kernel chips-media wave5 driver

Description

This security bulletin contains information about 1 vulnerability.

1) Out-of-bounds write (CVE-ID: CVE-2026-98882)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to potentially corrupt kernel memory and cause a denial of service.

The vulnerability exists due to insufficient range checking of frame-buffer indices in the Wave5 driver's wave5_vpu_dec_get_output_info() function when processing invalid decoder output information. A local user can potentially trigger an out-of-range frame-buffer access through invalid decoder output information to corrupt kernel memory and cause a denial of service.

Remediation

Install update from vendor's website.
