CVE-2026-68218

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.

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.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the dm1105 module from loading. See https://access.redhat.com/solutions/41278 for instructions.
