Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-68348)

CWE-ID: CWE-125 - Out-of-bounds read

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 an out-of-bounds read in the TAS2781 firmware parser when parsing malformed firmware description strings. A local user can supply a crafted firmware image without a NUL terminator to cause a denial of service.

The issue occurs because variable-length description strings are processed with strlen() before verifying that the terminator is present within the firmware buffer.
