Otherwise, garbage will\nleak from the stack to the firmware (when ssid is less than 32 bytes\nand/or when params->pmkid is set). Then, pass the params->pmkid to the\nfirmware (without it, the firmware caches a garbage PMKID on successful\nauthentication and denies a subsequent association request that includes\nthe PMKID)."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/broadcom/brcm80211/brcmfmac/cyw/core.c"],"versions":[{"version":"66f909308a7c05082919ff214a0bbe2a76aa0283","lessThan":"c2cf589c7d546557ed60c43f2ec014279265dfbf","status":"affected","versionType":"git"},{"version":"66f909308a7c05082919ff214a0bbe2a76aa0283","lessThan":"6fba6233e9ca7718661e53555a3961c58772c21a","status":"affected","versionType":"git"},{"version":"66f909308a7c05082919ff214a0bbe2a76aa0283","lessThan":"e2de8d5eb2984416affdd9559e55f37c7f1bbf47","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/broadcom/brcm80211/brcmfmac/cyw/core.c"],"versions":[{"version":"6.16","status":"affected"},{"version":"0","lessThan":"6.16","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc4","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.16","versionEndExcluding":"6.18.54"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.16","versionEndExcluding":"7.2.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.16","versionEndExcluding":"7.3-rc4"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c2cf589c7d546557ed60c43f2ec014279265dfbf"},{"url":"https://git.kernel.org/stable/c/6fba6233e9ca7718661e53555a3961c58772c21a"},{"url":"https://git.kernel.org/stable/c/e2de8d5eb2984416affdd9559e55f37c7f1bbf47"}],"title":"wifi: brcmfmac: cyw: pass PMKID to firmware if present","x_generator":{"engine":"bippy-1.2.0"}}}}
