Doc Text:	A flaw was found in the Linux kernel's AMD Sensor Fusion Hub (SFH) Human Interface Device (HID) driver. Improper memory cleanup during the device's initialization process can lead to memory errors and system instability. A local attacker with low privileges could exploit this to trigger page faults, cause the Btrfs file system to become read-only, or lead to Btrfs disk corruption, effectively causing a Denial of Service (DoS) and potential data loss.

Description OSIDB Bzimport 2024-11-08 13:48:18 UTC

In the Linux kernel, the following vulnerability has been resolved:

HID: amd_sfh: Switch to device-managed dmam_alloc_coherent()

Using the device-managed version allows to simplify clean-up in probe()
error path.

Additionally, this device-managed ensures proper cleanup, which helps to
resolve memory errors, page faults, btrfs going read-only, and btrfs
disk corruption.
