| CVE-2024-36940 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2026-10-15 | N/A | 7.8 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: pinctrl: core: delete incorrect free in pinctrl_enable() The "pctldev" struct is allocated in devm_pinctrl_register_and_init(). It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(), so freeing it in pinctrl_enable() will lead to a double free. The devm_pinctrl_dev_release() function frees the pindescs and destroys the mutex as well. | |||||
| CVE-2023-29469 | 2 Debian, Xmlsoft | 2 Debian Linux, Libxml2 | 2026-10-14 | N/A | 6.5 MEDIUM |
| An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\0' value). | |||||
| CVE-2023-25136 | 3 Fedoraproject, Netapp, Openbsd | 9 Fedora, 500f, 500f Firmware and 6 more | 2026-10-14 | N/A | 6.5 MEDIUM |
| OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address space. One third-party report states "remote code execution is theoretically possible." | |||||
| CVE-2025-62469 | 1 Microsoft | 3 Windows 11 24h2, Windows 11 25h2, Windows Server 2025 | 2026-10-14 | N/A | 7.0 HIGH |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Microsoft Brokering File System allows an authorized attacker to elevate privileges locally. | |||||
| CVE-2026-97830 | 1 Microsoft | 7 Windows 11 23h2, Windows 11 24h2, Windows 11 25h2 and 4 more | 2026-10-14 | N/A | 7.5 HIGH |
| Double free in Windows Internet Information Services allows an unauthorized attacker to deny service over a network. | |||||
| CVE-2022-42915 | 5 Apple, Fedoraproject, Haxx and 2 more | 13 Macos, Fedora, Curl and 10 more | 2026-10-14 | N/A | 8.1 HIGH |
| curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0. | |||||
| CVE-2022-40304 | 3 Apple, Netapp, Xmlsoft | 22 Ipados, Iphone Os, Macos and 19 more | 2026-10-14 | N/A | 7.8 HIGH |
| An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. | |||||
| CVE-2026-108104 | 2026-10-14 | N/A | 4.8 MEDIUM | ||
| Xerial snappy-java from 1.1.7.4 before 1.1.10.10 contains a double release vulnerability in SnappyFramedInputStream that returns pooled buffers twice when replacement allocation fails. Attackers can supply framed data with a large declared chunk length to trigger OutOfMemoryError, causing shared backing arrays that expose or overwrite other streams' decompressed data. | |||||
| CVE-2022-4450 | 2 Openssl, Stormshield | 2 Openssl, Stormshield Network Security | 2026-10-14 | N/A | 7.5 HIGH |
| The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the "name" (e.g. "CERTIFICATE"), any header data and the payload data. If the function succeeds then the "name_out", "header" and "data" arguments are populated with pointers to buffers containing the relevant decoded data. The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a buffer that has already been freed. If the caller also frees this buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service attack. The functions PEM_read_bio() and PEM_read() are simple wrappers around PEM_read_bio_ex() and therefore these functions are also directly affected. These functions are also called indirectly by a number of other OpenSSL functions including PEM_X509_INFO_read_bio_ex() and SSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL internal uses of these functions are not vulnerable because the caller does not free the header argument if PEM_read_bio_ex() returns a failure code. These locations include the PEM_read_bio_TYPE() functions as well as the decoders introduced in OpenSSL 3.0. The OpenSSL asn1parse command line application is also impacted by this issue. | |||||
| CVE-2022-2588 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2026-10-14 | N/A | 5.3 MEDIUM |
| It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0. | |||||

| CVE-2022-2327 | 2 Linux, Netapp | 11 Linux Kernel, H300s, H300s Firmware and 8 more | 2026-10-14 | N/A | 7.5 HIGH |
| io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859 | |||||

| In strongSwan before 6.0.7, identity parsing/cloning is mishandled. Parsed EAP-Identities that result in an empty but non-NULL encoding are not correctly cloned and trigger a double-free once the duplicates are destroyed. | |||||

| 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 | 3 Debian, Fedoraproject, Gnu | 3 Debian Linux, Fedora, Glibc | 2026-10-14 | 1.9 LOW | 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. | |||||

| 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-2020-36225 | 3 Apple, Debian, Openldap | 3 Macos, Debian Linux, Openldap | 2026-10-14 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was discovered in OpenLDAP before 2.4.57 leading to a double free and slapd crash in the saslAuthzTo processing, resulting in denial of service. | |||||

| Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3. | |||||
| CVE-2026-5759 | 2026-10-13 | N/A | 9.8 CRITICAL | ||
| A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders (src/serializers/decoders/*/decode_graph_entities.c) in FalkorDB before 4.18.1 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service or execute arbitrary code in the redis-server process by supplying a crafted RDB stream whose deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time. | |||||
