{"id":"CVE-2025-68173","summary":"ftrace: Fix softlockup in ftrace_module_enable","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nftrace: Fix softlockup in ftrace_module_enable\n\nA soft lockup was observed when loading amdgpu module.\nIf a module has a lot of tracable functions, multiple calls\nto kallsyms_lookup can spend too much time in RCU critical\nsection and with disabled preemption, causing kernel panic.\nThis is the same issue that was fixed in\ncommit d0b24b4e91fc (\"ftrace: Prevent RCU stall on PREEMPT_VOLUNTARY\nkernels\") and commit 42ea22e754ba (\"ftrace: Add cond_resched() to\nftrace_graph_set_hash()\").\n\nFix it the same way by adding cond_resched() in ftrace_module_enable.","modified":"2026-05-18T05:57:37.231514929Z","published":"2025-12-16T13:42:53.106Z","related":["SUSE-SU-2026:20838-1","SUSE-SU-2026:20931-1","SUSE-SU-2026:21284-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68173.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4099b98203d6b33d990586542fa5beee408032a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/40c8ee40e48a2c82c762539952ed8fc0571db5bf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e3c96010ade29bb340a5bdce8675f50c7f59001"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a1dd0abd741a8111260676da729825d6c1461a71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e81e6d6d99b16dae11adbeda5c996317942a940c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68173.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68173"},{"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":"b7ffffbb46f205e7727a18bcc7a46c3c2b534f7c"},{"fixed":"a1dd0abd741a8111260676da729825d6c1461a71"},{"fixed":"e81e6d6d99b16dae11adbeda5c996317942a940c"},{"fixed":"40c8ee40e48a2c82c762539952ed8fc0571db5bf"},{"fixed":"7e3c96010ade29bb340a5bdce8675f50c7f59001"},{"fixed":"4099b98203d6b33d990586542fa5beee408032a3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-68173.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.5.0"},{"fixed":"6.1.159"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.117"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.58"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.17.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-68173.json"}}],"schema_version":"1.7.5"}
