{"id":"DEBIAN-CVE-2021-46922","details":"In the Linux kernel, the following vulnerability has been resolved:  KEYS: trusted: Fix TPM reservation for seal/unseal  The original patch 8c657a0590de (\"KEYS: trusted: Reserve TPM for seal and unseal operations\") was correct on the mailing list:  https://lore.kernel.org/linux-integrity/20210128235621.127925-4-jarkko@kernel.org/  But somehow got rebased so that the tpm_try_get_ops() in tpm2_seal_trusted() got lost.  This causes an imbalanced put of the TPM ops and causes oopses on TIS based hardware.  This fix puts back the lost tpm_try_get_ops()","modified":"2026-09-15T09:02:30.506712321Z","published":"2024-02-27T10:15:07.053Z","upstream":["CVE-2021-46922"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2021-46922"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.38-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2021-46922.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.38-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2021-46922.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.38-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2021-46922.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
