CVE-2026-68218
Description
A flaw was found in the dm1105 PCI driver of the Linux kernel. This issue arises from the driver's failure to properly deallocate resources, specifically a workqueue, when the device is removed. This oversight can lead to a memory leak, which a local attacker could potentially exploit to cause a denial of service (DoS) by exhausting system memory.
Statement
This issue affects systems using the dm1105 DVB PCI adapter driver. The driver allocates a workqueue on probe but does not destroy it on remove, leaking memory. Systems without dm1105 hardware are not affected.
Mitigation
To mitigate this issue, prevent the dm1105 module from loading. See https://access.redhat.com/solutions/41278 for instructions.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
