The array is filled in mwifiex_update_chan_statistics()\nand then the user can query the data in mwifiex_cfg80211_dump_survey().\n\nThere are two potential issues here.  What if the user calls\nmwifiex_cfg80211_dump_survey() before the data has been filled in.\nAlso the mwifiex_update_chan_statistics() function doesn't necessarily\ninitialize the whole array.  Since the array was not initialized at\nthe start that could result in an information leak.\n\nAlso this array is pretty small.  It's a maximum of 900 bytes so it's\nmore appropriate to use kcalloc() instead vmalloc()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/marvell/mwifiex/cfg80211.c","drivers/net/wireless/marvell/mwifiex/main.c"],"versions":[{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"9eb0118b3470b4d2e4e3bbb1fc088b30c0285d65","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"05daef0442d28350a1a0d6d0e2cab4a7a91df475","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"acdf26a912190fc6746e2a890d7d0338190527b4","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"32c124c9c03aa755cbaf60ef7f76afd918d47659","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"9df29aa5637d94d24f7c5f054ef4feaa7b766111","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"06616410a3e5e6cd1de5b7cbc668f1a7edeedad9","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"5285b7009dc1e09d5bb9e05fae82e1a807882dbc","status":"affected","versionType":"git"},{"version":"bf35443314acb43fa8a3f9f8046e14cbe178762b","lessThan":"0e20450829ca3c1dbc2db536391537c57a40fe0b","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/marvell/mwifiex/cfg80211.c","drivers/net/wireless/marvell/mwifiex/main.c"],"versions":[{"version":"3.19","status":"affected"},{"version":"0","lessThan":"3.19","status":"unaffected","versionType":"semver"},{"version":"5.4.299","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.243","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.192","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.151","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.105","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.46","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.16.6","lessThanOrEqual":"6.16.*","status":"unaffected","versionType":"semver"},{"version":"6.17","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":"3.19","versionEndExcluding":"5.4.299"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.10.243"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.15.192"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.1.151"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.6.105"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.12.46"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.16.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9eb0118b3470b4d2e4e3bbb1fc088b30c0285d65"},{"url":"https://git.kernel.org/stable/c/05daef0442d28350a1a0d6d0e2cab4a7a91df475"},{"url":"https://git.kernel.org/stable/c/acdf26a912190fc6746e2a890d7d0338190527b4"},{"url":"https://git.kernel.org/stable/c/32c124c9c03aa755cbaf60ef7f76afd918d47659"},{"url":"https://git.kernel.org/stable/c/9df29aa5637d94d24f7c5f054ef4feaa7b766111"},{"url":"https://git.kernel.org/stable/c/06616410a3e5e6cd1de5b7cbc668f1a7edeedad9"},{"url":"https://git.kernel.org/stable/c/5285b7009dc1e09d5bb9e05fae82e1a807882dbc"},{"url":"https://git.kernel.org/stable/c/0e20450829ca3c1dbc2db536391537c57a40fe0b"}],"title":"wifi:
