If a command times out as the\ndevice is removed, command_timer_fn() runs concurrently with teardown and\ndereferences priv after it has been freed.\n\nThis is the same use-after-free that commit 03cc8f90d053 (\"wifi: libertas:\nfix use-after-free in lbs_free_adapter()\") fixed in the sibling libertas\ndriver. The libertas_tf variant has the identical pattern and was left\nunchanged. Use timer_delete_sync() so any in-flight callback completes\nbefore priv is freed."}],"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/libertas_tf/main.c"],"versions":[{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"bd75636681588c67006279abdb9a76a708b3ce29","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"2fba1d3b2f031a2c68e566a6d45cc5b7a8d6683d","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"9392fd5de555272449d3d8c63410ea00f8ec853a","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"4714e95f5d61cb9c5c7c6c4e68b618f37bc6ffcf","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"066b59e84f90d270cc15f0370166155aca507630","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"fcff712d0e3d183843ec3916470ee6cc3455baad","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"bcf7968cb97ce4312588042cf2712f04caff6d8f","status":"affected","versionType":"git"},{"version":"06b16ae5319251c26377afcb401e46056d5673f4","lessThan":"aa6dcd5c8dd9ba1d7d0f60093bcda41c0d6d438d","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/libertas_tf/main.c"],"versions":[{"version":"2.6.28","status":"affected"},{"version":"0","lessThan":"2.6.28","status":"unaffected","versionType":"semver"},{"version":"5.10.266","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.217","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.184","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":"6.18.40","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":"2.6.28","versionEndExcluding":"5.10.266"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"5.15.217"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"6.1.184"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"6.6.148"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"6.12.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.28","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bd75636681588c67006279abdb9a76a708b3ce29"},{"url":"https://git.kernel.org/stable/c/2fba1d3b2f031a2c68e566a6d45cc5b7a8d6683d"},{"url":"https://git.kernel.org/stable/c/9392fd5de555272449d3d8c63410ea00f8ec853a"},{"url":"https://git.kernel.org/stable/c/4714e95f5d61cb9c5c7c6c4e68b618f37bc6ffcf"},{"url":"https://git.kernel.org/stable/c/066b59e84f90d270cc15f0370166155aca507630"},{"url":"https://git.kernel.org/stable/c/fcff712d0e3d183843ec3916470ee6cc3455baad"},{"url":"https://git.kernel.org/stable/c/bcf7968cb97ce4312588042cf2712f04caff6d8f"},{"url":"https://git.kernel.org/stable/c/aa6dcd5c8dd9ba1d7d0f60093bcda41c0d6d438d"}],"title":"wifi: libertas_tf: fix use-after-free in lbtf_free_adapter()","x_generator":{"engine":"bippy-1.2.0"}}}}
