The call to\nof_node_put(nchangeset) can decrement the reference count to zero and\nfree the node if there are no other holders. After that, the code still\nuses 'parent' to check for the presence of a property and to read a\nstring property, leading to a use-after-free.\n\nFix this by moving the of_node_put() call after the last access to\n'parent', avoiding the UAF."}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.4,"baseSeverity":"HIGH"}}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/of/unittest.c"],"versions":[{"version":"1c668ea65506e67ce2eae07b69bb09fcdd86e309","lessThan":"37318d1a27c9cc5a70d3cd7e49e30ec86f2b8ca1","status":"affected","versionType":"git"},{"version":"1c668ea65506e67ce2eae07b69bb09fcdd86e309","lessThan":"7f0f0926f3010b10cff5e93446258f971e42f2fd","status":"affected","versionType":"git"},{"version":"1c668ea65506e67ce2eae07b69bb09fcdd86e309","lessThan":"6fdad20b7975bdc32e85b45f8f7c640f6687b81f","status":"affected","versionType":"git"},{"version":"1c668ea65506e67ce2eae07b69bb09fcdd86e309","lessThan":"faecdd423c27f0d6090156a435ba9dbbac0eaddb","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/of/unittest.c"],"versions":[{"version":"6.12","status":"affected"},{"version":"0","lessThan":"6.12","status":"unaffected","versionType":"semver"},{"version":"6.12.86","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.27","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.4","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"6.12","versionEndExcluding":"6.12.86"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"6.18.27"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"7.0.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/37318d1a27c9cc5a70d3cd7e49e30ec86f2b8ca1"},{"url":"https://git.kernel.org/stable/c/7f0f0926f3010b10cff5e93446258f971e42f2fd"},{"url":"https://git.kernel.org/stable/c/6fdad20b7975bdc32e85b45f8f7c640f6687b81f"},{"url":"https://git.kernel.org/stable/c/faecdd423c27f0d6090156a435ba9dbbac0eaddb"}],"title":"of: unittest: fix use-after-free in of_unittest_changeset()","x_generator":{"engine":"bippy-1.2.0"}}}}
