The loop checks if an element is a\nfgraph_stub to prevent using a fgraph_stub afterward.\n\nHowever, if the compiler reloads fgraph_array[] after this check, it might\nrace with an update to fgraph_array[] that introduces a fgraph_stub. This\ncould result in the stub being processed, but the stub contains a null\n\"func_hash\" field, leading to a NULL pointer dereference.\n\nTo ensure that the gops compared against the fgraph_stub matches the gops\nprocessed later, add a READ_ONCE(). A similar patch appears in commit\n63a8dfb (\"function_graph: Add READ_ONCE() when accessing fgraph_array[]\")."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["kernel/trace/fgraph.c"],"versions":[{"version":"37238abe3cb47b8daaa8706c9949f67b2a705cf1","lessThan":"b68b2a3fbacc7be720ef589d489bcacdd05c6d38","status":"affected","versionType":"git"},{"version":"37238abe3cb47b8daaa8706c9949f67b2a705cf1","lessThan":"d65474033740ded0a4fe9a097fce72328655b41d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["kernel/trace/fgraph.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.12.9","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.12.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.13"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b68b2a3fbacc7be720ef589d489bcacdd05c6d38"},{"url":"https://git.kernel.org/stable/c/d65474033740ded0a4fe9a097fce72328655b41d"}],"title":"fgraph: Add READ_ONCE() when accessing fgraph_array[]","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":4.7,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"id":"CVE-2024-57934","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2025-10-01T19:52:53.039611Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-476","description":"CWE-476 NULL Pointer Dereference"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-01T19:57:14.140Z"}}]}}
