{"id":"CVE-2025-68789","summary":"hwmon: (ibmpex) fix use-after-free in high/low store","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (ibmpex) fix use-after-free in high/low store\n\nThe ibmpex_high_low_store() function retrieves driver data using\ndev_get_drvdata() and uses it without validation. This creates a race\ncondition where the sysfs callback can be invoked after the data\nstructure is freed, leading to use-after-free.\n\nFix by adding a NULL check after dev_get_drvdata(), and reordering\noperations in the deletion path to prevent TOCTOU.","modified":"2026-03-31T17:29:37.758314Z","published":"2026-01-13T15:29:02.079Z","related":["MGASA-2026-0017","MGASA-2026-0018","SUSE-SU-2026:0447-1","SUSE-SU-2026:0472-1","SUSE-SU-2026:0587-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20555-1","SUSE-SU-2026:20599-1","SUSE-SU-2026:20615-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","openSUSE-SU-2026:20287-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68789.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ce9b7ae9d4d148672b35147aaf7987a4f82bb94"},{"type":"WEB","url":"https://git.kernel.org/stable/c/533ead425f8109b02fecc7e72d612b8898ec347a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5aa2139201667c1f644601e4529c4acd6bf8db5a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/68d62e5bebbd118b763e8bb210d5cf2198ef450c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6946c726c3f4c36f0f049e6f97e88c510b15f65d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa37adcf1d564ef58b9dfb01b6c36d35c5294bad"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68789.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68789"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"57c7c3a0fdea95eddcaeba31e7ca7dfc917682ab"},{"fixed":"3ce9b7ae9d4d148672b35147aaf7987a4f82bb94"},{"fixed":"533ead425f8109b02fecc7e72d612b8898ec347a"},{"fixed":"fa37adcf1d564ef58b9dfb01b6c36d35c5294bad"},{"fixed":"68d62e5bebbd118b763e8bb210d5cf2198ef450c"},{"fixed":"5aa2139201667c1f644601e4529c4acd6bf8db5a"},{"fixed":"6946c726c3f4c36f0f049e6f97e88c510b15f65d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68789.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.24"},{"fixed":"5.10.248"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"6.1.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.120"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.64"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68789.json"}}],"schema_version":"1.7.5"}
