{"id":"CVE-2026-68087","summary":"HID: wacom: use GFP_ATOMIC in wacom_wac_queue_flush()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: wacom: use GFP_ATOMIC in wacom_wac_queue_flush()\n\nwacom_wac_queue_flush() is called via the .raw_event callback\n(wacom_raw_event → wacom_wac_pen_serial_enforce → wacom_wac_queue_flush).\nFor USB HID devices, this callback is invoked from hid_irq_in(), which\nis a URB completion handler running in atomic context. Using GFP_KERNEL\nin this path can sleep, leading to a \"scheduling while atomic\" bug.\n\nUse GFP_ATOMIC instead. The existing code already handles allocation\nfailure by skipping the fifo entry and continuing.","modified":"2026-08-12T04:19:21.382417607Z","published":"2026-08-10T11:51:41.348Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68087.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/27c4dad1b7917b747bf080792a527997e3147c69"},{"type":"WEB","url":"https://git.kernel.org/stable/c/55f1ad573e34abf9a0443c34bc5a63d74edba7d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbe1e55629bfaabd4b2e8125b48dd3503d74ac8b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68087.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68087"},{"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":"5e013ad206895e72d7da41bc1ae89d8cb499c3aa"},{"fixed":"bbe1e55629bfaabd4b2e8125b48dd3503d74ac8b"},{"fixed":"27c4dad1b7917b747bf080792a527997e3147c69"},{"fixed":"55f1ad573e34abf9a0443c34bc5a63d74edba7d7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68087.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68087.json"}}],"schema_version":"1.9.0"}
