{"id":"CVE-2022-49583","summary":"iavf: Fix handling of dummy receive descriptors","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niavf: Fix handling of dummy receive descriptors\n\nFix memory leak caused by not handling dummy receive descriptor properly.\niavf_get_rx_buffer now sets the rx_buffer return value for dummy receive\ndescriptors. Without this patch, when the hardware writes a dummy\ndescriptor, iavf would not free the page allocated for the previous receive\nbuffer. This is an unlikely event but can still happen.\n\n[Jesse: massaged commit message]","modified":"2026-03-20T12:24:40.028097Z","published":"2025-02-26T02:23:20.108Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1241-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49583.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2918419c06088f6709ceb543feb01752779ade4c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6edb818732fc05fda495f5b3a749bd1cee01398b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a9f49e0060301a9bfebeca76739158d0cf91cdf6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6af94324911ef0846af1a5ce5e049ca736db34b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d88d59faf4e6f9cc4767664206afdb999b10ec77"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49583.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49583"},{"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":"efa14c3985828da3163f5372137cb64d992b0f79"},{"fixed":"d88d59faf4e6f9cc4767664206afdb999b10ec77"},{"fixed":"c6af94324911ef0846af1a5ce5e049ca736db34b"},{"fixed":"2918419c06088f6709ceb543feb01752779ade4c"},{"fixed":"6edb818732fc05fda495f5b3a749bd1cee01398b"},{"fixed":"a9f49e0060301a9bfebeca76739158d0cf91cdf6"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"2a51e334a0ade539e5b0fcfdbd8b43acb9c7547d"},{"last_affected":"833577ecf3451c7306abb48f221d365c2ee4cc1b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49583.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
