If the allocation of each member fails, the array itself\nis freed and returned with an error code. However, the array is later\nfreed again in si_dpm_fini() function which is called when the function\nreturns an error.\n\nThis leads to potential double free of the array adev->pm.dpm.ps, as\nwell as leak of its array members, since the members are not freed in\nthe allocation function and the array is not nulled when freed.\nIn addition adev->pm.dpm.num_ps, which keeps track of the allocated\narray member, is not updated until the member allocation is\nsuccessfully finished, this could also lead to either use after free,\nor uninitialized variable access in si_dpm_fini().\n\nFix this by postponing the free of the array until si_dpm_fini() and\nincrement adev->pm.dpm.num_ps everytime the array member is allocated."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c"],"versions":[{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"2615464854505188f909d0c07c37a6623693b5c7","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"6c5bdaa1325be7f04b79ea992ab216739192d342","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"c0e811c4ccf3b42705976285e3a94cc82dea7300","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"af832028af6f44c6c45645757079c4ed6884ade5","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"ca1ce206894dd976275c78ee38dbc19873f22de9","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"a5ce7051db044290b1a95045ff03c249005a3aa4","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"fd2eff8b9dcbe469c3b7bbbc7083ab5ed94de07b","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"43eb9b667b95f2a31c63e8949b0d2161b9be59c3","status":"affected","versionType":"git"},{"version":"841686df9f7d2942cfd94d024b8591fa3f74ef7c","lessThan":"f3fa2becf2fc25b6ac7cf8d8b1a2e4a86b3b72bd","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/gpu/drm/amd/pm/legacy-dpm/si_dpm.c"],"versions":[{"version":"4.9","status":"affected"},{"version":"0","lessThan":"4.9","status":"unaffected","versionType":"semver"},{"version":"4.9.318","lessThanOrEqual":"4.9.*","status":"unaffected","versionType":"semver"},{"version":"4.14.283","lessThanOrEqual":"4.14.*","status":"unaffected","versionType":"semver"},{"version":"4.19.247","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.198","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.121","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.46","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.17.14","lessThanOrEqual":"5.17.*","status":"unaffected","versionType":"semver"},{"version":"5.18.3","lessThanOrEqual":"5.18.*","status":"unaffected","versionType":"semver"},{"version":"5.19","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":"4.9","versionEndExcluding":"4.9.318"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"4.14.283"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"4.19.247"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.4.198"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.10.121"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.15.46"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.17.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.18.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/2615464854505188f909d0c07c37a6623693b5c7"},{"url":"https://git.kernel.org/stable/c/6c5bdaa1325be7f04b79ea992ab216739192d342"},{"url":"https://git.kernel.org/stable/c/c0e811c4ccf3b42705976285e3a94cc82dea7300"},{"url":"https://git.kernel.org/stable/c/af832028af6f44c6c45645757079c4ed6884ade5"},{"url":"https://git.kernel.org/stable/c/ca1ce206894dd976275c78ee38dbc19873f22de9"},{"url":"https://git.kernel.org/stable/c/a5ce7051db044290b1a95045ff03c249005a3aa4"},{"url":"https://git.kernel.org/stable/c/fd2eff8b9dcbe469c3b7bbbc7083ab5ed94de07b"},{"url":"https://git.kernel.org/stable/c/43eb9b667b95f2a31c63e8949b0d2161b9be59c3"},{"url":"https://git.kernel.org/stable/c/f3fa2becf2fc25b6ac7cf8d8b1a2e4a86b3b72bd"}],"title":"drm/amd/pm:
