{"id":"CVE-2026-23094","summary":"uacce: fix isolate sysfs check condition","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nuacce: fix isolate sysfs check condition\n\nuacce supports the device isolation feature. If the driver\nimplements the isolate_err_threshold_read and\nisolate_err_threshold_write callback functions, uacce will create\nsysfs files now. Users can read and configure the isolation policy\nthrough sysfs. Currently, sysfs files are created as long as either\nisolate_err_threshold_read or isolate_err_threshold_write callback\nfunctions are present.\n\nHowever, accessing a non-existent callback function may cause the\nsystem to crash. Therefore, intercept the creation of sysfs if\nneither read nor write exists; create sysfs if either is supported,\nbut intercept unsupported operations at the call site.","modified":"2026-04-02T17:29:43.001048Z","published":"2026-02-04T16:08:17.061Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23094.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/82821a681d5dcce31475a65190fc39ea8f372cc0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98eec349259b1fd876f350b1c600403bcef8f85d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ab05cdcac354b1b1139918f49c6418b9005d042"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fdbbb47d15ae17bf39fafec7e2028c1f8efba15e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23094.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23094"},{"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":"e3e289fbc0b520cf469469e8cdba84a50424eb65"},{"fixed":"9ab05cdcac354b1b1139918f49c6418b9005d042"},{"fixed":"fdbbb47d15ae17bf39fafec7e2028c1f8efba15e"},{"fixed":"82821a681d5dcce31475a65190fc39ea8f372cc0"},{"fixed":"98eec349259b1fd876f350b1c600403bcef8f85d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23094.json"}}],"schema_version":"1.7.5"}
