{"id":"CVE-2026-80948","summary":"wifi: iwlwifi: dvm: fix memory leak in iwl_op_mode_dvm_start()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: dvm: fix memory leak in iwl_op_mode_dvm_start()\n\nIn iwl_op_mode_dvm_start(), jumping to out_free_eeprom currently bypasses\nthe out_free_eeprom_blob label. Consequently, error paths triggered after\nsuccessfully parsing the EEPROM free priv-\u003envm_data but leak\npriv-\u003eeeprom_blob.\n\nFix this memory leak by reordering the error handling labels so\nthat out_free_eeprom falls through to out_free_eeprom_blob.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1-rc6.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\nsupported Intel DVM wireless hardware and firmware to test with, no\nruntime testing was able to be performed.","modified":"2026-09-14T03:45:49.403145841Z","published":"2026-09-11T19:42:19.048Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80948.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/67105abd6195a685a84dcb8a5daf54a1f4bfdb60"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84ba017a1e1ea7896ed1e3258c947bdbfc5299c5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ad2a9fdca4a7100472be82ee6048c616fc589720"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80948.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80948"},{"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":"26a7ca9a71a3f7e1826de96b1a1e907123e11b07"},{"fixed":"84ba017a1e1ea7896ed1e3258c947bdbfc5299c5"},{"fixed":"ad2a9fdca4a7100472be82ee6048c616fc589720"},{"fixed":"67105abd6195a685a84dcb8a5daf54a1f4bfdb60"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80948.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.6.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80948.json"}}],"schema_version":"1.9.0"}
