{"id":"CVE-2024-47732","summary":"crypto: iaa - Fix potential use after free bug","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: iaa - Fix potential use after free bug\n\nThe free_device_compression_mode(iaa_device, device_mode) function frees\n\"device_mode\" but it iss passed to iaa_compression_modes[i]-\u003efree() a few\nlines later resulting in a use after free.\n\nThe good news is that, so far as I can tell, nothing implements the\n-\u003efree() function and the use after free happens in dead code.  But, with\nthis fix, when something does implement it, we'll be ready.  :)","modified":"2026-04-02T12:20:25.977154Z","published":"2024-10-21T12:14:03.863Z","related":["SUSE-SU-2024:3984-1","SUSE-SU-2024:3986-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4387-1","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","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/47xxx/CVE-2024-47732.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b5d534b473e2c8d3e4560be2dd6c12a8eb9d61e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c66f0be993ba52410edab06124c54ecf143b05c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0d3b845a1b10b7b5abdad7ecc69d45b2aab3209"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/47xxx/CVE-2024-47732.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47732"},{"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":"b190447e0fa3ef7355480d641d078962e03768b4"},{"fixed":"b5d534b473e2c8d3e4560be2dd6c12a8eb9d61e9"},{"fixed":"c66f0be993ba52410edab06124c54ecf143b05c1"},{"fixed":"e0d3b845a1b10b7b5abdad7ecc69d45b2aab3209"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-47732.json"}}],"schema_version":"1.7.5"}
