The Ethernet connect path stores that\ndevice in mac->mc_dev and keeps it for the lifetime of the connected MAC\nobject.\n\nHowever, the disconnect path only disconnects and closes the MAC before\nfreeing the dpaa2_mac object. It does not drop the endpoint device\nreference stored in mac->mc_dev, so every successful connect leaks that\ndevice reference when the MAC is later disconnected.\n\nDrop the endpoint device reference after closing the MAC and before\nfreeing the dpaa2_mac object."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/freescale/dpaa2/dpaa2-eth.c"],"versions":[{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"6b6ffdb9ca4547a3c4c274aa3e25b6c68dbc62e1","status":"affected","versionType":"git"},{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"1974127776da46a000c61f36d4946799ea6d4f51","status":"affected","versionType":"git"},{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"915012e923316b8b5d5bf8fc771617b47bd7572d","status":"affected","versionType":"git"},{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"e23e4a3b9dfd893469c731318d409cdf04fb1ddf","status":"affected","versionType":"git"},{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"f112df0744e2d77baa68eeebb860021bbaaa022a","status":"affected","versionType":"git"},{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"a3cecf169cc652b558d08661bb6ce55e4c933ec0","status":"affected","versionType":"git"},{"version":"71947923089353f23f4f210864903c4dcf2c1696","lessThan":"b4b201cc93ff70150853aba03e14d314d1980ca0","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/ethernet/freescale/dpaa2/dpaa2-eth.c"],"versions":[{"version":"5.5","status":"affected"},{"version":"0","lessThan":"5.5","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":"5.5","versionEndExcluding":"5.15.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.1.183"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.6.148"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.12.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"6.18.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6b6ffdb9ca4547a3c4c274aa3e25b6c68dbc62e1"},{"url":"https://git.kernel.org/stable/c/1974127776da46a000c61f36d4946799ea6d4f51"},{"url":"https://git.kernel.org/stable/c/915012e923316b8b5d5bf8fc771617b47bd7572d"},{"url":"https://git.kernel.org/stable/c/e23e4a3b9dfd893469c731318d409cdf04fb1ddf"},{"url":"https://git.kernel.org/stable/c/f112df0744e2d77baa68eeebb860021bbaaa022a"},{"url":"https://git.kernel.org/stable/c/a3cecf169cc652b558d08661bb6ce55e4c933ec0"},{"url":"https://git.kernel.org/stable/c/b4b201cc93ff70150853aba03e14d314d1980ca0"}],"title":"dpaa2-eth: put MAC endpoint device on disconnect","x_generator":{"engine":"bippy-1.2.0"}}}}
