Resource exhaustion in Linux kernel - CVE-2026-43287

Published: May 9, 2026


Vulnerability identifier: #VU130896
CSH Severity: Low
CVSS v4: 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]
CVE-ID: CVE-2026-43287
CWE-ID: CWE-400
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to improper resource management in DRM_IOCTL_MODE_CREATEPROPBLOB when allocating arbitrary-sized property blobs backed by kernel memory. A local user can create property blobs to cause a denial of service.

The issue can lead to unbounded kernel memory consumption and potentially system-wide out-of-memory conditions.
