{"id":"CVE-2026-31524","summary":"HID: asus: avoid memory leak in asus_report_fixup()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: asus: avoid memory leak in asus_report_fixup()\n\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.\n\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.\n\nAlso fix a harmless out-of-bounds read by copying only the original\ndescriptor size.","modified":"2026-05-18T05:59:50.426801876Z","published":"2026-04-22T13:54:38.389Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31524.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2bad24c17742fc88973d6aea526ce1353f5334a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2e4fe6b15c2f390c023b20d728b1a3fe7ea4f973"},{"type":"WEB","url":"https://git.kernel.org/stable/c/726765b43deb2b4723869d673cc5fc6f7a3b2059"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a6d6e4d8af044f94fa97e97af5ff2771e1fbebd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84724ac4821a160d47b84289adf139023027bdbb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a41cc7c1668e44ff2c2d36f9a6353253ffc43e3c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ede95cfcab8064d9a08813fbd7ed42cea8843dcf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f20f17cffbe34fb330267e0f8084f5565f807444"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31524.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31524"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5703e52cc711bc01e72cf12b86a126909c79d213"},{"fixed":"726765b43deb2b4723869d673cc5fc6f7a3b2059"},{"fixed":"ede95cfcab8064d9a08813fbd7ed42cea8843dcf"},{"fixed":"2e4fe6b15c2f390c023b20d728b1a3fe7ea4f973"},{"fixed":"f20f17cffbe34fb330267e0f8084f5565f807444"},{"fixed":"7a6d6e4d8af044f94fa97e97af5ff2771e1fbebd"},{"fixed":"a41cc7c1668e44ff2c2d36f9a6353253ffc43e3c"},{"fixed":"84724ac4821a160d47b84289adf139023027bdbb"},{"fixed":"2bad24c17742fc88973d6aea526ce1353f5334a3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31524.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.14.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.168"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.131"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.80"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.21"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31524.json"}}],"schema_version":"1.7.5"}
