CVE-2020-8231 6 Debian, Haxx, Oracle and 3 more 6 Debian Linux, Libcurl, Communications Cloud Native Core Policy and 3 more 2026-10-14 7.5 High
Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending data.
CVE-2020-1752 5 Canonical, Debian, Gnu and 2 more 10 Ubuntu Linux, Debian Linux, Glibc and 7 more 2026-10-14 7 High
A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32.
CVE-2020-1712 3 Debian, Redhat, Systemd Project 8 Debian Linux, Ceph Storage, Discovery and 5 more 2026-10-14 7.8 High
A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages.
CVE-2019-20795 2 Canonical, Iproute2 Project 2 Ubuntu Linux, Iproute2 2026-10-14 4.4 Medium
iproute2 before 5.1.0 has a use-after-free in get_netnsid_from_name in ip/ipnetns.c. NOTE: security relevance may be limited to certain uses of setuid that, although not a default, are sometimes a configuration option offered to end users. Even when setuid is used, other factors (such as C library configuration) may block exploitability.
CVE-2019-5481 7 Debian, Fedoraproject, Haxx and 4 more 15 Debian Linux, Fedora, Curl and 12 more 2026-10-14 9.8 Critical
Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.
CVE-2019-5018 3 Canonical, Redhat, Sqlite 3 Ubuntu Linux, Enterprise Linux, Sqlite 2026-10-14 8.1 High
An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
CVE-2016-5131 8 Apple, Canonical, Debian and 5 more 18 Iphone Os, Mac Os X, Tvos and 15 more 2026-10-14 8.8 High
Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function.
CVE-2016-4658 3 Apple, Redhat, Xmlsoft 6 Iphone Os, Mac Os X, Tvos and 3 more 2026-10-14 N/A
xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document.
CVE-2016-3189 2 Bzip, Python 2 Bzip2, Python 2026-10-14 6.5 Medium
Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start of the block.
CVE-2026-69765 1 Microsoft 2 Windows Server 2025, Windows Server 2025 (server Core Installation) 2026-10-14 8.8 High
Use after free in Windows Storport Miniport Driver allows an unauthorized attacker to execute code over a network.
CVE-2026-85197 1 Redhat 2 Enterprise Linux, Enterprise Linux Eus 2026-10-14 7.6 High
A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle (MITM) attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file body is being read asynchronously. This can lead to memory corruption, potentially resulting in information disclosure or arbitrary code execution.
CVE-2026-19548 2 Gnu, Redhat 7 Binutils, Adminutil, Enterprise Linux and 4 more 2026-10-14 5.5 Medium
Multiple Use-After-Free vulnerabilities were found in the add_archive_element function in ld/ldmain.c of the GNU linker (ld), a component of binutils. The root cause is that plugin_maybe_claim() in ld/plugin.c frees the original BFD object via bfd_close/_bfd_delete_bfd when entry->the_bfd->my_archive == NULL, but the caller retains both the original abfd parameter and a shallow copy (orig_input.the_bfd) as dangling pointers. These dangling pointers are subsequently dereferenced at three distinct locations in add_archive_element: 1. Line ~1442: accessing abfd->my_archive via bfd_usrdata(abfd->my_archive) 2. Line ~1493: multiple accesses to abfd and abfd->my_archive in a conditional check and bfd_get_filename call 3. Line ~1525: dereferencing the shallow copy orig_input.the_bfd->my_archive in trace/verbose logging The vulnerability is triggered when LTO plugins are active (link_info.lto_plugin_active is true) and the input object has abfd->my_archive == NULL, which is a valid state for standalone object files. Red Hat builds binutils with --enable-plugins and --enable-lto, confirming the vulnerable code path is compiled in and reachable. An attacker who can supply a crafted object or archive file to a build process using LTO-enabled linking could exploit this flaw to cause a denial of service (linker crash via segmentation fault). Arbitrary code execution is theoretically possible through heap manipulation but is substantially mitigated by hardening measures including stack protector, FORTIFY_SOURCE, ASLR, and PIE. The attack surface is limited to build-time environments — the linker is a development tool not exposed in production runtime. The most realistic exploitation scenario is a supply chain attack introducing a crafted object file as a build dependency in CI/CD pipelines or development environments.

CVE-2026-94453 2026-10-13 7.5 High
Libreswan's pluto daemon has a use-after-free vulnerability when a client connecting using IKE over TCP closes the connection and another packet (retransmit or malicious) is received for the same tuple. IKE state is retained in memory after the client closes the connection, storing a pointer to iface_endpoint inside ike_sa.sa->st_iface_endpoint. Once this invalid pointer is used, the daemon crashes and restarts. This vulnerability can be triggered before the remote peer has authenticated itself. Continued exploitation can lead to a denial of service. Remote code execution could be possible. The IKE over TCP option is not enabled by default; only configurations that contain listen-tcp=yes are affected.
CVE-2026-105725 1 Microsoft 1 Windows Security App 2026-10-13 7 High
Use after free in Windows Security App allows an authorized attacker to elevate privileges locally.
CVE-2026-83914 1 Microsoft 15 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 12 more 2026-10-13 8.1 High
Use after free in Microsoft XML allows an unauthorized attacker to execute code over a network.
CVE-2026-69150 2026-10-13 N/A
KeePassXC is a cross-platform community-driven port of the Windows application KeePass Password Safe. Prior to 2.8.0-beta1, KeePass1 / KDB legacy import retains raw Entry pointers in m_entryUuids after deleting metastream entries. When a crafted, unlockable .kdb file contains an earlier metastream entry followed by a KPX_CUSTOM_ICONS_4 metastream that references the earlier UUID, parseCustomIcons4() calls Entry::setIcon through the stale pointer, causing a heap use-after-free with a controlled write and a reliable process crash. This issue is fixed in version 2.8.0-beta1.
