{"id":"CVE-2024-53085","summary":"tpm: Lock TPM chip in tpm_pm_suspend() first","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntpm: Lock TPM chip in tpm_pm_suspend() first\n\nSetting TPM_CHIP_FLAG_SUSPENDED in the end of tpm_pm_suspend() can be racy\naccording, as this leaves window for tpm_hwrng_read() to be called while\nthe operation is in progress. The recent bug report gives also evidence of\nthis behaviour.\n\nAadress this by locking the TPM chip before checking any chip-\u003eflags both\nin tpm_pm_suspend() and tpm_hwrng_read(). Move TPM_CHIP_FLAG_SUSPENDED\ncheck inside tpm_get_random() so that it will be always checked only when\nthe lock is reserved.","modified":"2026-11-13T04:03:20.586231047Z","published":"2024-11-19T17:45:14.209Z","related":["SUSE-SU-2024:4314-1","SUSE-SU-2024:4315-1","SUSE-SU-2024:4316-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4367-1","SUSE-SU-2024:4376-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:0035-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53085.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/9265fed6db601ee2ec47577815387458ef4f047a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc203fe416abdd1c29da594565a7c3c4e979488e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cfaf83501a0cbb104499c5b0892ee5ebde4e967f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53085.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53085"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"99d46450625590d410f86fe4660a5eff7d3b8343"},{"fixed":"cfaf83501a0cbb104499c5b0892ee5ebde4e967f"},{"fixed":"bc203fe416abdd1c29da594565a7c3c4e979488e"},{"fixed":"9265fed6db601ee2ec47577815387458ef4f047a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7cd46930b8bf37b84777410ac21bfdf1179021d5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"eeda114c92c7b2db69878cdf27163750fd57cfe2"}]}],"versions":["v6.1.192","v6.1.191","v6.1.190","v6.1.189","v6.1.188","v6.1.187","v6.1.186","v6.1.185","v6.1.184","v6.1.183","v6.1.182","v6.1.181","v6.1.180","v6.1.179","v6.1.178","v6.1.177","v6.1.176","v6.1.175","v6.1.174","v6.1.173","v6.1.172","v6.1.171","v6.1.170","v6.1.169","v6.1.168","v6.1.167","v6.1.166","v6.1.165","v6.1.164","v6.1.163","v6.1.162","v6.1.161","v6.1.160","v6.1.159","v6.1.158","v6.1.157","v6.1.156","v6.1.155","v6.1.154","v6.1.153","v6.1.152","v6.1.151","v6.1.150","v6.1.149","v6.1.148","v6.1.147","v6.1.146","v6.1.145","v6.1.144","v6.1.143","v6.1.142","v6.1.141","v6.1.140","v6.1.139","v6.1.138","v6.1.137","v6.1.136","v6.1.135","v6.1.134","v6.1.133","v6.1.132","v6.1.131","v6.1.130","v6.1.129","v6.1.128","v6.1.127","v6.1.126","v6.1.125","v6.1.124","v6.1.123","v6.1.122","v6.1.121","v6.1.120","v6.1.119","v6.1.118","v6.1.117","v6.1.116","v6.1.115","v6.1.114","v6.1.113","v6.1.112","v6.1.111","v6.1.110","v6.1.109","v6.1.108","v6.1.107","v6.1.106","v6.1.105","v6.1.104","v6.1.103","v6.1.102","v6.1.101","v6.1.100","v6.1.99","v6.1.98","v6.1.97","v6.1.96","v6.1.95","v6.1.94","v6.1.93","v6.1.92","v6.1.91","v6.1.90","v6.1.89","v6.1.88","v6.1.87","v6.1.86","v6.1.85","v6.1.84","v6.1.83","v6.1.82","v6.1.81","v6.1.80","v6.1.79","v6.1.78","v6.1.77","v6.1.76","v6.1.75","v6.1.74","v6.1.73","v6.1.72","v6.1.71","v6.1.70","v6.1.69","v6.1.68","v6.1.67","v6.1.66","v6.1.65","v6.1.64","v6.1.63","v6.1.62","v6.1.61","v6.1.60","v6.1.59","v6.1.58","v6.1.57","v6.1.56","v6.1.55","v6.1.54","v6.1.53","v6.1.52","v6.1.51","v6.1.50","v6.1.49","v6.1.48","v6.1.47","v6.1.46","v6.1.45","v6.1.44","v6.1.43","v6.1.42","v6.1.41","v6.1.40","v6.1.39","v6.1.38","v6.1.37","v6.1.36","v6.1.35","v6.1.34","v6.1.33","v6.1.32","v6.1.31","v6.3.13","v6.3.12","v6.3.11","v6.3.10","v6.3.9","v6.3.8","v6.3.7","v6.3.6","v6.3.5"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-53085.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.31"},{"fixed":"6.2"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.3.5"},{"fixed":"6.4"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.4.0"},{"fixed":"6.6.64"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.11.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-53085.json"}}],"schema_version":"1.9.2"}
