In the Linux kernel, the following vulnerability has been resolved:
HID: asus: avoid memory leak in asus_report_fixup()
The asus_report_fixup() function was returning a newly allocated kmemdup()-allocated buffer, but never freeing it. Switch to devm_kzalloc() to ensure the memory is managed and freed automatically when the device is removed.
The caller of report_fixup() does not take ownership of the returned pointer, but it is permitted to return a pointer whose lifetime is at least that of the input buffer.
Also fix a harmless out-of-bounds read by copying only the original descriptor size.
AnalysisAI
Memory leak and out-of-bounds read in the asus_report_fixup() HID driver function allows local authenticated attackers with limited privileges to cause denial of service through memory exhaustion. The vulnerability affects the ASUS HID device driver across multiple Linux kernel versions, where kmemdup()-allocated buffers were not freed properly and an out-of-bounds read could access memory beyond the original descriptor size. A patch is available from Linux kernel maintainers switching to devm_kzalloc() for proper memory lifecycle management.
Technical ContextAI
The vulnerability exists in the Linux kernel's HID (Human Interface Device) subsystem, specifically in the ASUS-specific report fixup handler (drivers/hid/hid-asus.c). The asus_report_fixup() function handles HID report descriptor normalization for ASUS devices. The root cause is improper memory management: kmemdup() allocated a buffer to duplicate the HID report descriptor, but the returned pointer was never freed, causing accumulated memory leaks as devices are connected and disconnected. Additionally, the function performed an out-of-bounds read by copying beyond the original descriptor size. The fix employs devm_kzalloc(), a device-managed allocation function that automatically frees memory when the associated HID device is removed, eliminating both the leak and the boundary violation. This affects the HID subsystem's device driver infrastructure rather than a protocol or core kernel component, making the impact limited to systems using ASUS HID devices.
RemediationAI
Apply kernel updates to patched versions: Linux 5.10.253 or later, 5.15.203 or later, 6.1.168 or later, 6.6.131 or later, 6.12.80 or later, 6.18.21 or later, 6.19.11 or later, or 7.0 stable release and later. Patches are available from kernel.org stable branches via the Git commit references listed in the CVE advisory (git.kernel.org/stable/c/[commit-hash]). For systems unable to immediately upgrade, the primary workaround is to blacklist or avoid loading the asus_hid driver if ASUS HID devices are not present (echo 'blacklist hid_asus' >> /etc/modprobe.d/blacklist.conf and rebuild initramfs if the driver is built-in), though this eliminates ASUS device functionality. Alternatively, if ASUS devices are connected infrequently, reduce exposure by minimizing device hotplug cycles. Systems using distribution-provided kernels should check with their vendor's security advisory portal for patched kernel releases (Debian, Ubuntu, RHEL, SUSE, etc. each maintain their own stable branches with backported fixes). Kernel rebuilds from source with patches are an option for systems requiring immediate remediation and cannot wait for vendor releases.
