For instance, if a session\nhas refcount == 1, and one thread tries to free this session via:\n\n    kref_put(&sess->refcount, destroy_session);\n\nthe reference count will get decremented, and the next step would be to\ncall destroy_session(). However, if in another thread,\namdtee_open_session() is called before destroy_session() has completed\nexecution, alloc_session() may return 'sess' that will be freed up\nlater in destroy_session() leading to use-after-free in\namdtee_open_session.\n\nTo fix this issue, treat decrement of sess->refcount and removal of\n'sess' from session list in destroy_session() as a critical section, so\nthat it is executed atomically."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/tee/amdtee/core.c"],"versions":[{"version":"757cc3e9ff1d72d014096399d6e2bf03974d9da1","lessThan":"da7ce52a2f6c468946195b116615297d3d113a27","status":"affected","versionType":"git"},{"version":"757cc3e9ff1d72d014096399d6e2bf03974d9da1","lessThan":"1680c82929bc14d706065f123dab77f2f1293116","status":"affected","versionType":"git"},{"version":"757cc3e9ff1d72d014096399d6e2bf03974d9da1","lessThan":"60c3e7a00db954947c265b55099c21b216f2a05c","status":"affected","versionType":"git"},{"version":"757cc3e9ff1d72d014096399d6e2bf03974d9da1","lessThan":"1c95574350cd63bc3c5c2fa06658010768f2a0ce","status":"affected","versionType":"git"},{"version":"757cc3e9ff1d72d014096399d6e2bf03974d9da1","lessThan":"f4384b3e54ea813868bb81a861bf5b2406e15d8f","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/tee/amdtee/core.c"],"versions":[{"version":"5.6","status":"affected"},{"version":"0","lessThan":"5.6","status":"unaffected","versionType":"semver"},{"version":"5.10.199","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.136","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.59","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.5.8","lessThanOrEqual":"6.5.*","status":"unaffected","versionType":"semver"},{"version":"6.6","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":"5.6","versionEndExcluding":"5.10.199"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.6","versionEndExcluding":"5.15.136"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.6","versionEndExcluding":"6.1.59"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.6","versionEndExcluding":"6.5.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.6","versionEndExcluding":"6.6"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/da7ce52a2f6c468946195b116615297d3d113a27"},{"url":"https://git.kernel.org/stable/c/1680c82929bc14d706065f123dab77f2f1293116"},{"url":"https://git.kernel.org/stable/c/60c3e7a00db954947c265b55099c21b216f2a05c"},{"url":"https://git.kernel.org/stable/c/1c95574350cd63bc3c5c2fa06658010768f2a0ce"},{"url":"https://git.kernel.org/stable/c/f4384b3e54ea813868bb81a861bf5b2406e15d8f"}],"title":"tee: amdtee: fix use-after-free vulnerability in amdtee_close_session","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T23:03:20.580Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/da7ce52a2f6c468946195b116615297d3d113a27","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/1680c82929bc14d706065f123dab77f2f1293116","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/60c3e7a00db954947c265b55099c21b216f2a05c","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/1c95574350cd63bc3c5c2fa06658010768f2a0ce","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/f4384b3e54ea813868bb81a861bf5b2406e15d8f","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-08-08T18:34:27.896164Z","id":"CVE-2023-52503","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-08-08T18:34:37.754Z"}}]}}
