{"id":"CVE-2026-89627","summary":"HID: roccat: free buffered reports when destroying device","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: roccat: free buffered reports when destroying device\n\nroccat_report_event() duplicates each report with kmemdup() and stores\nthe allocation in a circular-buffer slot. The allocation is released only\nwhen that slot is reused.\n\nThe device destruction paths free struct roccat_device without releasing\nreports still stored in cbuf[]. This makes those allocations unreachable\nand leaks up to ROCCAT_CBUF_SIZE report buffers per device.\n\nAdd a small destructor that frees every buffered report before freeing the\ndevice, and use it in both paths that can destroy a registered device.","modified":"2026-09-25T18:26:56.417105041Z","published":"2026-09-11T19:45:23.479Z","related":["openSUSE-SU-2026:11880-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89627.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4cb3ff31d237ad1f515455c497ef07d7172d912b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/690da9177e64bcfda2f4c0b5b8465178e4a236d8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/943b8dc2c6044c01e36395f51bb809a4b6bdfd22"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b3cc411daa50b39ba5706492a80a5a0804d9c85f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbff0ccbff360a5498075525005f6a913239a3d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cebb20b9a29cfc90bf56e54337333084f85a69dd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da00eac19feef209c9591e48c860afc2014603be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fbb5a60f5c31b5625f0d89a79912fbcb2559289b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89627.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89627"},{"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":"206f5f2fcb5ff5bb0c60f9e9189937f3ca03e378"},{"fixed":"cebb20b9a29cfc90bf56e54337333084f85a69dd"},{"fixed":"690da9177e64bcfda2f4c0b5b8465178e4a236d8"},{"fixed":"b3cc411daa50b39ba5706492a80a5a0804d9c85f"},{"fixed":"4cb3ff31d237ad1f515455c497ef07d7172d912b"},{"fixed":"943b8dc2c6044c01e36395f51bb809a4b6bdfd22"},{"fixed":"da00eac19feef209c9591e48c860afc2014603be"},{"fixed":"fbb5a60f5c31b5625f0d89a79912fbcb2559289b"},{"fixed":"bbff0ccbff360a5498075525005f6a913239a3d7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-89627.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.35"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-89627.json"}}],"schema_version":"1.9.0"}
