  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nHID: asus: avoid memory leak in asus_report_fixup()\nThe asus_report_fixup() function was returning a newly allocated\nkmemdup()-allocated buffer, but never freeing it.  Switch to\ndevm_kzalloc() to ensure the memory is managed and freed automatically\nwhen the device is removed.\nThe caller of report_fixup() does not take ownership of the returned\npointer, but it is permitted to return a pointer whose lifetime is at\nleast that of the input buffer.\nAlso fix a harmless out-of-bounds read by copying only the original\ndescriptor size.", "A flaw was found in the Linux kernel's Human Interface Device (HID) subsystem, specifically within the ASUS HID driver. The `asus_report_fixup()` function did not properly manage allocated memory, resulting in a memory leak (CWE-401). This issue could allow a local attacker to consume system resources, potentially leading to a denial of service. A minor out-of-bounds read (CWE-125) was also identified, though it is considered harmless." ],
