CVE-2024-21808

Vulnerability

Description

CVE-2024-21808 is an improper buffer restrictions vulnerability in Intel(R) VPL (Video Processing Library) software versions prior to 24.1.4. This weakness stems from insufficient bounds checking or memory management within the library's data handling routines, which can lead to memory corruption when processing specially crafted input [1].

Exploitation

To exploit this issue, an attacker must have authenticated access to the local system. The attack vector is local, meaning the attacker needs a user account on the affected machine. The exploitation requires Intel VPL software to be installed and in use, and the attacker would likely need to invoke the vulnerable component with malicious parameters or data to trigger the buffer restriction flaw [1].

Impact

Successful exploitation could allow an authenticated user to escalate their privileges on the system. This means an attacker could gain higher-level access rights than they are normally permitted, potentially leading to full control over the affected host, including the ability to execute arbitrary code with elevated privileges [1].

Mitigation

Intel has addressed this vulnerability in Intel VPL software version 24.1.4 and later. Users are strongly advised to update to the latest version to mitigate the risk. The advisory notes that no workarounds are available, and updating is the only remediation [1].
