{"id":"CVE-2025-23158","summary":"media: venus: hfi: add check to handle incorrect queue size","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: venus: hfi: add check to handle incorrect queue size\n\nqsize represents size of shared queued between driver and video\nfirmware. Firmware can modify this value to an invalid large value. In\nsuch situation, empty_space will be bigger than the space actually\navailable. Since new_wr_idx is not checked, so the following code will\nresult in an OOB write.\n...\nqsize = qhdr-\u003eq_size\n\nif (wr_idx \u003e= rd_idx)\n empty_space = qsize - (wr_idx - rd_idx)\n....\nif (new_wr_idx \u003c qsize) {\n memcpy(wr_ptr, packet, dwords \u003c\u003c 2) --\u003e OOB write\n\nAdd check to ensure qsize is within the allocated size while\nreading and writing packets into the queue.","modified":"2026-04-02T12:45:23.687644Z","published":"2025-05-01T12:55:43.804Z","related":["SUSE-SU-2025:01964-1","SUSE-SU-2025:01965-1","SUSE-SU-2025:02000-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20408-1","SUSE-SU-2025:20413-1","SUSE-SU-2025:20419-1","SUSE-SU-2025:20421-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/23xxx/CVE-2025-23158.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/101a86619aab42bb61f2253bbf720121022eab86"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1b86c1917e16bafbbb08ab90baaff533aa36c62d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/32af5c1fdb9bc274f52ee0472d3b060b18e4aab4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/40084302f639b3fe954398c5ba5ee556b7242b54"},{"type":"WEB","url":"https://git.kernel.org/stable/c/679424f8b31446f90080befd0300ea915485b096"},{"type":"WEB","url":"https://git.kernel.org/stable/c/69baf245b23e20efda0079238b27fc63ecf13de1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a45957bcde529169188929816775a575de77d84f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cf5f7bb4e0d786f4d9d50ae6b5963935eab71d75"},{"type":"WEB","url":"https://git.kernel.org/stable/c/edb89d69b1438681daaf5ca90aed3242df94cc96"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/23xxx/CVE-2025-23158.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-23158"},{"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":"d96d3f30c0f2f564f6922bf4ccdf4464992e31fb"},{"fixed":"1b86c1917e16bafbbb08ab90baaff533aa36c62d"},{"fixed":"a45957bcde529169188929816775a575de77d84f"},{"fixed":"32af5c1fdb9bc274f52ee0472d3b060b18e4aab4"},{"fixed":"cf5f7bb4e0d786f4d9d50ae6b5963935eab71d75"},{"fixed":"40084302f639b3fe954398c5ba5ee556b7242b54"},{"fixed":"679424f8b31446f90080befd0300ea915485b096"},{"fixed":"edb89d69b1438681daaf5ca90aed3242df94cc96"},{"fixed":"101a86619aab42bb61f2253bbf720121022eab86"},{"fixed":"69baf245b23e20efda0079238b27fc63ecf13de1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-23158.json"}}],"schema_version":"1.7.5"}
