The\nsecond one is stored in port->netdev and later used by the remove path\nfor unregister_hdlc_device() and free_netdev().\n\nThis means that the registered netdev is not the same object that is\nunregistered and freed on remove. It also leaks the first allocation if\nthe second alloc_hdlcdev() call fails, and the first allocation is not\nchecked before ndev is used.\n\nOlder code allocated the HDLC netdev only once and stored the same object\nin both the local variable and port->netdev. The buggy conversion split\nthis into two alloc_hdlcdev() calls. A later rename changed the local\nvariable name to ndev, but the underlying mismatch remained.\n\nFix this by allocating the HDLC netdev only once and assigning the same\nobject to port->netdev."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wan/ixp4xx_hss.c"],"versions":[{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"77d925b948ee594a79afe66f85bb94b67940140b","status":"affected","versionType":"git"},{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"8f4c3c384092becbf4835a3f8ed8a3df1f544578","status":"affected","versionType":"git"},{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"fd0b939ebd1eee29945a539c5ed65c35dddac8d6","status":"affected","versionType":"git"},{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"ffba16e6f55948d94b7f16aa113d587c1c4c0643","status":"affected","versionType":"git"},{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"3f85fcd520aa703824b1958f35169925ddae2558","status":"affected","versionType":"git"},{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"91850f582783098415a334f8bd0a84c87ff15a8c","status":"affected","versionType":"git"},{"version":"99ebe65eb9c0ada015931d239d9f2d1dc8897fee","lessThan":"db818b0e8af7bac16860116a19c341a63d6677b4","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/wan/ixp4xx_hss.c"],"versions":[{"version":"5.14","status":"affected"},{"version":"0","lessThan":"5.14","status":"unaffected","versionType":"semver"},{"version":"5.15.217","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.178","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.145","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.97","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"5.14","versionEndExcluding":"5.15.217"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.1.178"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.6.145"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.12.97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/77d925b948ee594a79afe66f85bb94b67940140b"},{"url":"https://git.kernel.org/stable/c/8f4c3c384092becbf4835a3f8ed8a3df1f544578"},{"url":"https://git.kernel.org/stable/c/fd0b939ebd1eee29945a539c5ed65c35dddac8d6"},{"url":"https://git.kernel.org/stable/c/ffba16e6f55948d94b7f16aa113d587c1c4c0643"},{"url":"https://git.kernel.org/stable/c/3f85fcd520aa703824b1958f35169925ddae2558"},{"url":"https://git.kernel.org/stable/c/91850f582783098415a334f8bd0a84c87ff15a8c"},{"url":"https://git.kernel.org/stable/c/db818b0e8af7bac16860116a19c341a63d6677b4"}],"title":"net: ixp4xx_hss: fix duplicate HDLC netdev allocation","x_generator":{"engine":"bippy-1.2.0"}}}}
