{"id":"CVE-2026-90378","summary":"wifi: mt76: mt792x: Fix memory leak in SDIO TX path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt792x: Fix memory leak in SDIO TX path\n\nWhen tx_prepare_skb() returns an error in the SDIO TX path, the\nskb is not freed, leading to a memory leak. This can occur when\nzero-length frames (such as WNM NULL frames) are dropped to prevent\npotential hardware TX hangs.\n\nFix this by properly releasing the skb with ieee80211_tx_status_ext()\nwhen tx_prepare_skb() fails.","modified":"2026-09-19T03:47:28.993399797Z","published":"2026-09-17T16:09:16.655Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90378.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6a342db7a6502bc6781579145e05d4d4731786ab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6a8000c76dc34490a2bb321ad1a5f882a2ccab7c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/808f2767d4217a5b96f674288573b9b89d432eed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ef1351209d42b7d96604f2a13d7ea8215a24e07"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b64d196280aff8494ba6fb387e37b18479c99b83"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2c7f16f2c62f79f7c381e500afa7123580742a5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ddf6a17d8e3d0dbb841c13c10d7c1340a138a80d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90378.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90378"},{"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":"b747fa343817fd322b4463dda99d28fc51e19c52"},{"fixed":"b64d196280aff8494ba6fb387e37b18479c99b83"},{"fixed":"9ef1351209d42b7d96604f2a13d7ea8215a24e07"},{"fixed":"c2c7f16f2c62f79f7c381e500afa7123580742a5"},{"fixed":"6a8000c76dc34490a2bb321ad1a5f882a2ccab7c"},{"fixed":"ddf6a17d8e3d0dbb841c13c10d7c1340a138a80d"},{"fixed":"6a342db7a6502bc6781579145e05d4d4731786ab"},{"fixed":"808f2767d4217a5b96f674288573b9b89d432eed"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90378.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.12.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90378.json"}}],"schema_version":"1.9.0"}
