CVE-2023-53454: HID: multitouch: Correct devm device reference for hidinput input_dev name

Noroxi assessment

Priority: Monitor (action score 31/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Linux Linux 15ec7cb55e7d88755aa01d44a7a1015a42bfce86, 1d7833db9fd118415dace2ca157bfa603dec9c8c, 2763732ec1e68910719c75b6b896e11b6d3d622b.

Low priority for now. Upgrade to Linux Linux 15ec7cb55e7d88755aa01d44a7a1015a42bfce86, 1d7833db9fd118415dace2ca157bfa603dec9c8c, 2763732ec1e68910719c75b6b896e11b6d3d622b or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: HID: multitouch: Correct devm device reference for hidinput input_dev name Reference the HID device rather than the input device for the devm allocation of the input_dev name. Referencing the input_dev would lead to a use-after-free when the input_dev was unregistered and subsequently fires a uevent that depends on the name. At the point of firing the uevent, the name would be freed by devres management. Use devm_kasprintf to simplify the logic for allocating memory and formatting the input_dev name string.
