{"id":"CVE-2024-31082","details":"A heap-based buffer over-read vulnerability was found in the X.org server's ProcAppleDRICreatePixmap() function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a different endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory values and then transmit them back to the client until encountering an unmapped page, resulting in a crash. Despite the attacker's inability to control the specific memory copied into the replies, the small length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds reads.","modified":"2026-04-10T05:12:24.370247Z","published":"2024-04-04T14:15:10Z","related":["CGA-wqcr-fx69-5wqp","SUSE-SU-2024:1199-1","SUSE-SU-2024:1260-1","SUSE-SU-2024:1261-1","SUSE-SU-2024:1262-1","openSUSE-SU-2024:13828-1"],"references":[{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2271999"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2024-31082"},{"type":"WEB","url":"https://lists.x.org/archives/xorg-announce/2024-April/003497.html"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/03/13"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/12/10"}],"schema_version":"1.7.5"}
