CVE-2026-68218Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: media: pci: dm1105: Free allocated workqueue Destroy allocated workqueue in remove() callback to free its resources, thus fixing memory leak. 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. Red Hat severity: Low — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness…
