{"id":"AZL-103829","summary":"CVE-2026-97413 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/rtrs-srv: Fix integer underflow in process_read and process_write\n\nusr_len is read from a network-supplied message field (le16_to_cpu)\nand used to compute data_len = off - usr_len without validating that\nusr_len \u003c= off. A malicious RDMA client can send usr_len \u003e off causing\nan integer underflow, resulting in data_len wrapping to a huge size_t\nvalue which is then passed to the rdma_ev callback as a memory length,\nleading to out-of-bounds memory access.\n\nFix by reading and validating usr_len \u003c= off before rtrs_srv_get_ops_ids()\nin both process_read() and process_write(), ensuring the early return\npath acquires no reference and has no resource leak.","modified":"2026-09-25T14:15:54.426832881Z","published":"2026-09-24T17:17:18Z","upstream":["CVE-2026-97413"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97413"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103829.json"}}],"schema_version":"1.9.0"}
