Several early probe failures then unwind\nthrough wanxl_pci_remove_one(), including failure to allocate the coherent\nstatus area or to restore the DMA mask.\n\nwanxl_pci_remove_one() unconditionally calls wanxl_reset(), and\nwanxl_reset() dereferences card->plx.  On those early failures card->plx\nis still NULL, so the error path can dereference a NULL MMIO pointer.\n\nOnly issue the hardware reset once the BAR mapping exists.  The remaining\ncleanup in wanxl_pci_remove_one() already checks whether later resources\nwere allocated.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wan/wanxl.c"],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"ef394eeb9d5ec6db8d979eec6d27f56c2ebc6523","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"3d9617d856ebddcdddbab0ce877c397420f59f55","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"897e289db1e4d00ca6419cfe733c646492147270","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"f4834132773f15ffb255127499c8443947fa7d0f","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"b9e2ff70e96acf83693b27987e0390bad9f83efa","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"59cbe6cfa0fa23c192351cc284e30707309f6741","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"2fe22d58b3797d741570f9873b26653fd511576c","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"91957b89da995607cb654b1f9a3c126ddbaee10f","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/wanxl.c"],"versions":[{"version":"2.6.12","status":"affected"},{"version":"0","lessThan":"2.6.12","status":"unaffected","versionType":"semver"},{"version":"5.10.265","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.216","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.183","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.148","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.101","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.42","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.6","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":"2.6.12","versionEndExcluding":"5.10.265"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.15.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.1.183"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.6.148"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.12.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.18.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ef394eeb9d5ec6db8d979eec6d27f56c2ebc6523"},{"url":"https://git.kernel.org/stable/c/3d9617d856ebddcdddbab0ce877c397420f59f55"},{"url":"https://git.kernel.org/stable/c/897e289db1e4d00ca6419cfe733c646492147270"},{"url":"https://git.kernel.org/stable/c/f4834132773f15ffb255127499c8443947fa7d0f"},{"url":"https://git.kernel.org/stable/c/b9e2ff70e96acf83693b27987e0390bad9f83efa"},{"url":"https://git.kernel.org/stable/c/59cbe6cfa0fa23c192351cc284e30707309f6741"},{"url":"https://git.kernel.org/stable/c/2fe22d58b3797d741570f9873b26653fd511576c"},{"url":"https://git.kernel.org/stable/c/91957b89da995607cb654b1f9a3c126ddbaee10f"}],"title":"wan: wanxl: Only reset hardware after BAR mapping","x_generator":{"engine":"bippy-1.2.0"}}}}
