{"id":"CVE-2026-43144","summary":"wifi: brcmfmac: Fix potential kernel oops when probe fails","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: Fix potential kernel oops when probe fails\n\nWhen probe of the sdio brcmfmac device fails for some reasons (i.e.\nmissing firmware), the sdiodev-\u003ebus is set to error instead of NULL, thus\nthe cleanup later in brcmf_sdio_remove() tries to free resources via\ninvalid bus pointer. This happens because sdiodev-\u003ebus is set 2 times:\nfirst in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix\nthis by chaning the brcmf_sdio_probe() function to return the error code\nand set sdio-\u003ebus only there.","modified":"2026-07-08T08:09:34.535461849Z","published":"2026-05-06T11:27:28.220Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43144.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/243307a0d1b0d01538e202c00454c28b21d4432e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/379aac7ee8240848aa35f605b06addb4617c863e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64ccb0aac41c5055780c2a58bbe2c1b362ceccde"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43144.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43144"},{"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":"0ff0843310b74e565901d85f849fb308c3b1f220"},{"fixed":"64ccb0aac41c5055780c2a58bbe2c1b362ceccde"},{"fixed":"379aac7ee8240848aa35f605b06addb4617c863e"},{"fixed":"243307a0d1b0d01538e202c00454c28b21d4432e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43144.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43144.json"}}],"schema_version":"1.7.5"}
