The\nproblem is, this object is not stored as drvdata with the device; since the\nkfree function will accept a NULL pointer, the memory for the\nvfio_matrix_dev object is never freed.\n\nSince the device being released is contained within the vfio_matrix_dev\nobject, the container_of macro will be used to retrieve its pointer."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/s390/crypto/vfio_ap_drv.c"],"versions":[{"version":"1fde573413b549d52183382e639c1d6ce88f5959","lessThan":"5195de1d5f66b276683240a896783f7f43c4f664","status":"affected","versionType":"git"},{"version":"1fde573413b549d52183382e639c1d6ce88f5959","lessThan":"ee17dea3072dec0bc34399a32fa884e26342e4ea","status":"affected","versionType":"git"},{"version":"1fde573413b549d52183382e639c1d6ce88f5959","lessThan":"aa2bff25e9bb10c935c7ffe3d5f5975bdccb1749","status":"affected","versionType":"git"},{"version":"1fde573413b549d52183382e639c1d6ce88f5959","lessThan":"6a40fda14b4be3e38f03cc42ffd4efbc64fb3e67","status":"affected","versionType":"git"},{"version":"1fde573413b549d52183382e639c1d6ce88f5959","lessThan":"7b6a02f5bf15931464c79dfd487c57f76aae3496","status":"affected","versionType":"git"},{"version":"1fde573413b549d52183382e639c1d6ce88f5959","lessThan":"8f8cf767589f2131ae5d40f3758429095c701c84","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/s390/crypto/vfio_ap_drv.c"],"versions":[{"version":"4.20","status":"affected"},{"version":"0","lessThan":"4.20","status":"unaffected","versionType":"semver"},{"version":"5.4.240","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.177","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.106","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.23","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.2.10","lessThanOrEqual":"6.2.*","status":"unaffected","versionType":"semver"},{"version":"6.3","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":"4.20","versionEndExcluding":"5.4.240"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.10.177"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.15.106"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.1.23"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.2.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/5195de1d5f66b276683240a896783f7f43c4f664"},{"url":"https://git.kernel.org/stable/c/ee17dea3072dec0bc34399a32fa884e26342e4ea"},{"url":"https://git.kernel.org/stable/c/aa2bff25e9bb10c935c7ffe3d5f5975bdccb1749"},{"url":"https://git.kernel.org/stable/c/6a40fda14b4be3e38f03cc42ffd4efbc64fb3e67"},{"url":"https://git.kernel.org/stable/c/7b6a02f5bf15931464c79dfd487c57f76aae3496"},{"url":"https://git.kernel.org/stable/c/8f8cf767589f2131ae5d40f3758429095c701c84"}],"title":"s390/vfio-ap: fix memory leak in vfio_ap device driver","x_generator":{"engine":"bippy-1.2.0"}}}}
