{"id":"CVE-2024-57985","summary":"firmware: qcom: scm: Cleanup global '__scm' on probe failures","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: qcom: scm: Cleanup global '__scm' on probe failures\n\nIf SCM driver fails the probe, it should not leave global '__scm'\nvariable assigned, because external users of this driver will assume the\nprobe finished successfully.  For example TZMEM parts ('__scm-\u003emempool')\nare initialized later in the probe, but users of it (__scm_smc_call())\nrely on the '__scm' variable.\n\nThis fixes theoretical NULL pointer exception, triggered via introducing\nprobe deferral in SCM driver with call trace:\n\n  qcom_tzmem_alloc+0x70/0x1ac (P)\n  qcom_tzmem_alloc+0x64/0x1ac (L)\n  qcom_scm_assign_mem+0x78/0x194\n  qcom_rmtfs_mem_probe+0x2d4/0x38c\n  platform_probe+0x68/0xc8","modified":"2026-04-02T12:25:27.696037Z","published":"2025-02-27T02:07:09.983Z","related":["USN-7521-2"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/57xxx/CVE-2024-57985.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1e76b546e6fca7eb568161f408133904ca6bcf4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/390d3baeba51a126f75c97b90ec28b9384ce4b84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/faf1715798fe72b79e4432ce8c6d03ca69765425"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/57xxx/CVE-2024-57985.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-57985"},{"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":"40289e35ca525f29a03989352ab207b6a9675475"},{"fixed":"390d3baeba51a126f75c97b90ec28b9384ce4b84"},{"fixed":"faf1715798fe72b79e4432ce8c6d03ca69765425"},{"fixed":"1e76b546e6fca7eb568161f408133904ca6bcf4f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-57985.json"}}],"schema_version":"1.7.5"}
