Description
This security bulletin contains information about 1 vulnerability.
1) Resource exhaustion (CVE-ID: CVE-2026-43287)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 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/E:U/U:Clear
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.
Remediation
Install update from vendor's website.
