{"id":"CVE-2026-74299","summary":"RDMA/core: Fix FRMR aging push to queue error flow","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/core: Fix FRMR aging push to queue error flow\n\nAging pools with pinned handles requires moving handles from the\nactive queue to a non-empty inactive queue that might fail on new page\nallocation, we are currently not handling the fault and leaking any mkey\nthat fails the push.\n\nFix by Introducing push_queue_to_queue_locked() that fills the\ndestination's partial tail page from the source and then splices the\nremaining source pages onto the destination, performing no allocation.\n\nReplace the per-handle move loop in age_pinned_pool() and the\nopen-coded splice in pool_aging_work() with calls to the helper.\nAs the helper cannot fail under memory pressure, removing a class of\nGFP_ATOMIC allocations under the pool lock and simplifying the error\nflow.","modified":"2026-08-18T03:31:20.734489410Z","published":"2026-08-15T05:58:02.688Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74299.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/c6936506ed556ce3ccad36ab999baf2764dd7d25"},{"type":"WEB","url":"https://git.kernel.org/stable/c/edf133d28fc43f7f8b0da43a8d5b93fdf8073d35"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74299.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74299"},{"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":"020d189d16a62ed56115cce7e255459cf0eeb4e6"},{"fixed":"edf133d28fc43f7f8b0da43a8d5b93fdf8073d35"},{"fixed":"c6936506ed556ce3ccad36ab999baf2764dd7d25"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74299.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74299.json"}}],"schema_version":"1.9.0"}
