{"id":"AZL-100712","summary":"CVE-2026-89582 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnx2x: fix double free in bnx2x_init_firmware() error path\n\nbnx2x_init_firmware() frees bp-\u003einit_ops, bp-\u003einit_data and\nbp-\u003einit_ops_offsets in its error path without setting them to NULL.\nThe cleanup function bnx2x_release_firmware() frees the same three\npointers unconditionally, so if init_firmware fails and\nrelease_firmware is later called (e.g. from __bnx2x_remove or through\nthe function state machine), all three are freed a second time.\n\nSet each pointer to NULL after kfree() in the error path so that the\nsubsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-op.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:42Z","upstream":["CVE-2026-89582"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89582"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-100712.json"}}],"schema_version":"1.9.0"}
