Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2026-72089)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service or disclose sensitive information.
The vulnerability exists due to an out-of-bounds read in fw_log_print_lines() when processing a firmware log with a size smaller than its header. A local user can supply a crafted firmware log to cause a denial of service or disclose sensitive information.
A zero-sized log can cause callers to loop forever on the same header.
Remediation
Install update from vendor's website.
