Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: HID: playstation: Add missing check for input_ff_create_memless The… (CVE-2026-45969)
A vulnerability in the Linux kernel's HID subsystem related to the PlayStation driver was resolved. The issue involved the ps_gamepad_create() function calling input_ff_create_memless() without checking its return value, potentially causing incorrect behavior or crashes when force feedback effects are triggered. This flaw has been fixed in updated Linux kernel versions. The vulnerability has a medium severity with a CVSS score of 5.5 and does not impact confidentiality or integrity but can cause availability issues. Multiple Linux kernel versions are affected, and patches are available from Ubuntu as part of broader Linux kernel security updates.
AI Analysis
Technical Summary
CVE-2026-45969 addresses a flaw in the Linux kernel's HID PlayStation driver where the ps_gamepad_create() function invokes input_ff_create_memless() without verifying its return value. This missing check can lead to incorrect behavior or system crashes when force feedback (FF) effects are activated. The vulnerability affects numerous Linux kernel versions prior to 5.15.0-186.196 and various specific builds enumerated in the advisory. Ubuntu has released patches as part of their Linux kernel security updates (USN-8492-1 and USN-8492-2), which include fixes for this and other vulnerabilities across multiple kernel subsystems. Users are advised to update to the patched kernel versions and reboot to apply fixes.
Potential Impact
The vulnerability can cause system instability or crashes (availability impact) when force feedback effects are triggered on PlayStation controllers due to unchecked return values in the kernel driver. There is no impact on confidentiality or integrity. No known exploits are reported in the wild. The medium severity rating reflects the potential for denial of service but not data compromise.
Mitigation Recommendations
A patch is available and should be applied by updating the Linux kernel to the fixed versions provided by the vendor (Ubuntu). After updating, a system reboot is required to complete remediation. Due to ABI changes, third-party kernel modules must be recompiled and reinstalled. Users should follow the vendor's update instructions and verify installation of the patched kernel packages corresponding to their distribution and hardware platform.

Technical Analysis
CVE-2026-45969 addresses a flaw in the Linux kernel's HID PlayStation driver where the ps_gamepad_create() function invokes input_ff_create_memless() without verifying its return value. This missing check can lead to incorrect behavior or system crashes when force feedback (FF) effects are activated. The vulnerability affects numerous Linux kernel versions prior to 5.15.0-186.196 and various specific builds enumerated in the advisory. Ubuntu has released patches as part of their Linux kernel security updates (USN-8492-1 and USN-8492-2), which include fixes for this and other vulnerabilities across multiple kernel subsystems. Users are advised to update to the patched kernel versions and reboot to apply fixes.
Potential Impact
The vulnerability can cause system instability or crashes (availability impact) when force feedback effects are triggered on PlayStation controllers due to unchecked return values in the kernel driver. There is no impact on confidentiality or integrity. No known exploits are reported in the wild. The medium severity rating reflects the potential for denial of service but not data compromise.
Mitigation Recommendations
A patch is available and should be applied by updating the Linux kernel to the fixed versions provided by the vendor (Ubuntu). After updating, a system reboot is required to complete remediation. Due to ABI changes, third-party kernel modules must be recompiled and reinstalled. Users should follow the vendor's update instructions and verify installation of the patched kernel packages corresponding to their distribution and hardware platform.
