{"cve":"CVE-2024-57930","nvd":{"published":"2025-01-21T12:15:26.600","modified":"2026-06-17T08:14:15.550","status":"Modified","description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Have process_string() also allow arrays\n\nIn order to catch a common bug where a TRACE_EVENT() TP_fast_assign()\nassigns an address of an allocated string to the ring buffer and then\nreferences it in TP_printk(), which can be executed hours later when the\nstring is free, the function test_event_printk() runs on all events as\nthey are registered to make sure there's no unwanted dereferencing.\n\nIt calls process_string() to handle cases in TP_printk() format that has\n\"%s\". It returns whether or not the string is safe. But it can have some\nfalse positives.\n\nFor instance, xe_bo_move() has:\n\n TP_printk(\"move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s\",\n            __entry->move_lacks_source ? \"yes\" : \"no\", __entry->bo, __entry->size,\n            xe_mem_type_to_name[__entry->old_placement],\n            xe_mem_type_to_name[__entry->new_placement], __get_str(device_id))\n\nWhere the \"%s\" references into xe_mem_type_to_name[]. This is an array of\npointers that should be safe for the event to access. Instead of flagging\nthis as a bad reference, if a reference points to an array, where the\nrecord field is the index, consider it safe.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/3bcdc9039a6e9e6e47ed689a37b8d57894a3c571","https://git.kernel.org/stable/c/631b1e09e213c86d5a4ce23d45c81af473bb0ac7","https://git.kernel.org/stable/c/92bd18c74624e5eb9f96e70076aa46293f4b626f","https://git.kernel.org/stable/c/a64e5295ebc4afdefe69cdf16cc286a60ff8ba4b","https://git.kernel.org/stable/c/afc6717628f959941d7b33728570568b4af1c4b8"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:58:41.599736885+00:00"},"epss":{"cve":"CVE-2024-57930","score":0.00204,"percentile":0.10391,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
