{"id":"CVE-2026-31746","summary":"s390/zcrypt: Fix memory leak with CCA cards used as accelerator","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/zcrypt: Fix memory leak with CCA cards used as accelerator\n\nTests showed that there is a memory leak if CCA cards are used as\naccelerator for clear key RSA requests (ME and CRT). With the last\nrework for the memory allocation the AP messages are allocated by\nap_init_apmsg() but for some reason on two places (ME and CRT) the\nolder allocation was still in place. So the first allocation simple\nwas never freed.","modified":"2026-08-12T03:51:30.265357247Z","published":"2026-05-01T14:14:40.196Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31746.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/586222c37d4027dbf60a604fbe820184fee7c1c9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ace37bfec3822033e59fff390f2ff99fc96ebe4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8d46f17c2fc7d25c18e60c008928aecab26184d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31746.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31746"},{"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":"57db62a130ce69e6f3a870cf1119d8f860391f97"},{"fixed":"586222c37d4027dbf60a604fbe820184fee7c1c9"},{"fixed":"ace37bfec3822033e59fff390f2ff99fc96ebe4f"},{"fixed":"c8d46f17c2fc7d25c18e60c008928aecab26184d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31746.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.22"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31746.json"}}],"schema_version":"1.9.0"}
