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.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els9.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els9.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els9.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els9.x86_64" ], "known_affected": [ "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els1.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els1.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els5.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els5.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els7.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els7.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els1.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els1.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els5.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els5.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els7.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els7.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2024-31080" } ], "release_date": "2024-04-03T00:00:00Z", "remediations": [ { "category": "vendor_fix", "date": "2025-11-20T15:18:38.020131Z", "details": "Details on how to apply the fix are available at: https://cve.tuxcare.com/els/releases/CLSA-2025:1763651916", "product_ids": [ "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els9.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els9.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els9.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els9.x86_64" ], "url": "https://cve.tuxcare.com/els/releases/CLSA-2025:1763651916" }, { "category": "none_available", "details": "Affected", "product_ids": [ "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els1.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els1.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els5.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els5.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els7.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els7.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els1.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els1.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els5.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els5.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els7.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els7.x86_64" ] } ], "scores": [ { "cvss_v3": { "attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 7.3, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "LOW", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H", "version": "3.1" }, "products": [ "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els9.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-0:21.1.3-7.el9.tuxcare.els9.x86_64", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els9.i686", "AlmaLinux-9.2:xorg-x11-server-Xwayland-devel-0:21.1.3-7.el9.tuxcare.els9.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Important" } ] } ] }
