{"id":"CVE-2023-52606","summary":"powerpc/lib: Validate size for vector operations","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npowerpc/lib: Validate size for vector operations\n\nSome of the fp/vmx code in sstep.c assume a certain maximum size for the\ninstructions being emulated. The size of those operations however is\ndetermined separately in analyse_instr().\n\nAdd a check to validate the assumption on the maximum size of the\noperations, so as to prevent any unintended kernel stack corruption.","modified":"2026-04-11T12:46:33.111926Z","published":"2024-03-06T06:45:31.257Z","related":["SUSE-SU-2024:1466-1","SUSE-SU-2024:1480-1","SUSE-SU-2024:1490-1","USN-6818-2","USN-6819-2"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52606.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0580f4403ad33f379eef865c2a6fe94de37febdf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/28b8ba8eebf26f66d9f2df4ba550b6b3b136082c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/42084a428a139f1a429f597d44621e3a18f3e414"},{"type":"WEB","url":"https://git.kernel.org/stable/c/848e1d7fd710900397e1d0e7584680c1c04e3afd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8f9abaa6d7de0a70fc68acaedce290c1f96e2e59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/abd26515d4b767ba48241eea77b28ce0872aef3e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/beee482cc4c9a6b1dcffb2e190b4fd8782258678"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de4f5ed63b8a199704d8cdcbf810309d7eb4b36b"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52606.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52606"},{"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":"c22435a5f3d8f85ea162ae523a6ba60a58521ba5"},{"fixed":"42084a428a139f1a429f597d44621e3a18f3e414"},{"fixed":"0580f4403ad33f379eef865c2a6fe94de37febdf"},{"fixed":"beee482cc4c9a6b1dcffb2e190b4fd8782258678"},{"fixed":"de4f5ed63b8a199704d8cdcbf810309d7eb4b36b"},{"fixed":"abd26515d4b767ba48241eea77b28ce0872aef3e"},{"fixed":"28b8ba8eebf26f66d9f2df4ba550b6b3b136082c"},{"fixed":"848e1d7fd710900397e1d0e7584680c1c04e3afd"},{"fixed":"8f9abaa6d7de0a70fc68acaedce290c1f96e2e59"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52606.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.14.0"},{"fixed":"4.19.307"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.269"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.149"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.77"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.7.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52606.json"}}],"schema_version":"1.7.5"}
