The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __verify_map_perm_classperms and hashtab_map).
CVE-2021-36084 3 Fedoraproject, Redhat, Selinux Project 3 Fedora, Enterprise Linux, Selinux 2026-10-14 3.3 Low
The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __cil_verify_classpermission and __cil_pre_verify_helper).
CVE-2021-33574 5 Debian, Fedoraproject, Gnu and 2 more 21 Debian Linux, Fedora, Glibc and 18 more 2026-10-14 9.8 Critical
The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact.
CVE-2021-28041 4 Fedoraproject, Netapp, Openbsd and 1 more 11 Fedora, Cloud Backup, Hci Compute Node and 8 more 2026-10-14 7.1 High
ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host.
CVE-2021-27645 4 Debian, Fedoraproject, Gnu and 1 more 4 Debian Linux, Fedora, Glibc and 1 more 2026-10-14 2.5 Low
The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2026-10-14 9.1 Critical
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
CVE-2026-92388 2026-10-14 6.5 Medium
A flaw was found in curl. A remote malicious server can cause a Denial of Service (DoS) or memory corruption in applications that enable File Transfer Protocol (FTP) wildcard matching. When a wildcard listing operation fails, curl does not properly reset its internal callback handlers before the connection handle is reused or duplicated. An application that subsequently reuses or clones this corrupted handle may experience an immediate application crash or unsafe memory access.
CVE-2026-104342 2026-10-14 7.8 High
Adobe Framemaker is affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2026-103843 2026-10-14 7.8 High
Substance3D - Stager is affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2021-22901 6 Haxx, Netapp, Oracle and 3 more 35 Curl, Active Iq Unified Manager, Cloud Backup and 32 more 2026-10-14 8.1 High
curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives. If the connection is used by multiple transfers (like with a reused HTTP/1.1 connection or multiplexed HTTP/2 connection) that first transfer object might be freed before the new session is established on that connection and then the function will access a memory buffer that might be freed. When using that memory, libcurl might even call a function pointer in the object, making it possible for a remote code execution if the server could somehow manage to get crafted memory content into the correct place in memory.
CVE-2021-20232 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Enterprise Linux 2026-10-14 9.8 Critical
A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences.
CVE-2021-20231 4 Fedoraproject, Gnu, Netapp and 1 more 5 Fedora, Gnutls, Active Iq Unified Manager and 2 more 2026-10-14 9.8 Critical
A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences.
CVE-2021-20227 2 Oracle, Sqlite 7 Communications Network Charging And Control, Enterprise Manager For Oracle Database, Jd Edwards Enterpriseone Tools and 4 more 2026-10-14 5.5 Medium
A flaw was found in SQLite's SELECT query functionality (src/select.c). This flaw allows an attacker who is capable of running SQL queries locally on the SQLite database to cause a denial of service or possible code execution by triggering a use-after-free. The highest threat from this vulnerability is to system availability.
CVE-2026-109711 1 Mozilla 2 Firefox, Thunderbird 2026-10-14 5.4 Medium
Use-after-free in the Graphics: Canvas2D component. This vulnerability was fixed in Firefox 158, Firefox ESR 153.5, Thunderbird 158, and Thunderbird 153.5.

There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability.
CVE-2021-3516 6 Debian, Fedoraproject, Netapp and 3 more 10 Debian Linux, Fedora, Clustered Data Ontap and 7 more 2026-10-14 7.8 High
There's a flaw in libxml2's xmllint in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity, and availability.
