CVE-2023-52927 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-10-15 7.8 High
In the Linux kernel, the following vulnerability has been resolved: netfilter: allow exp not to be removed in nf_ct_find_expectation Currently nf_conntrack_in() calling nf_ct_find_expectation() will remove the exp from the hash table. However, in some scenario, we expect the exp not to be removed when the created ct will not be confirmed, like in OVS and TC conntrack in the following patches. This patch allows exp not to be removed by setting IPS_CONFIRMED in the status of the tmpl.
CVE-2023-45322 1 Xmlsoft 1 Libxml2 2026-10-15 6.5 Medium
libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail."
CVE-2023-40283 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2026-10-15 7.8 High
An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.
CVE-2023-35827 1 Linux 1 Linux Kernel 2026-10-15 7.0 High
An issue was discovered in the Linux kernel through 6.3.8. A use-after-free was found in ravb_remove in drivers/net/ethernet/renesas/ravb_main.c.
CVE-2023-32233 3 Linux, Netapp, Redhat 9 Linux Kernel, Hci Baseboard Management Controller, Enterprise Linux and 6 more 2026-10-15 7.8 High
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.
CVE-2023-29469 3 Debian, Redhat, Xmlsoft 5 Debian Linux, Enterprise Linux, Jboss Core Services and 2 more 2026-10-14 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-2023-27537 4 Broadcom, Haxx, Netapp and 1 more 13 Brocade Fabric Operating System Firmware, Libcurl, Active Iq Unified Manager and 10 more 2026-10-14 5.9 Medium
A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free.
CVE-2023-25136 4 Fedoraproject, Netapp, Openbsd and 1 more 10 Fedora, 500f, 500f Firmware and 7 more 2026-10-14 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-2026-78457 1 Microsoft 9 Windows 11 24h2, Windows 11 24h2, Windows 11 25h2 and 6 more 2026-10-14 7 High
Use after free in Windows Security App allows an authorized attacker to elevate privileges locally.
CVE-2026-32078 1 Microsoft 22 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 19 more 2026-10-14 7.8 High
Use after free in Windows Projected File System allows an authorized attacker to elevate privileges locally.
CVE-2026-32074 1 Microsoft 22 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 19 more 2026-10-14 7.8 High
Double free in Windows Projected File System allows an authorized attacker to elevate privileges locally.
CVE-2026-32070 1 Microsoft 30 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 27 more 2026-10-14 7 High
Use after free in Windows Common Log File System Driver allows an authorized attacker to elevate privileges locally.
CVE-2026-32069 1 Microsoft 22 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 19 more 2026-10-14 7.8 High
Double free in Windows Projected File System allows an authorized attacker to elevate privileges locally.
CVE-2023-5197 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-10-14 7.8 High
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.
CVE-2023-5178 3 Linux, Netapp, Redhat 10 Linux Kernel, Active Iq Unified Manager, Solidfire \& Hci Management Node and 7 more 2026-10-14 8.8 High
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation.
CVE-2023-4921 3 Debian, Linux, Redhat 10 Debian Linux, Linux Kernel, Enterprise Linux and 7 more 2026-10-14 7.8 High
A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8.
CVE-2023-4813 4 Fedoraproject, Gnu, Netapp and 1 more 23 Fedora, Glibc, Active Iq Unified Manager and 20 more 2026-10-14 5.9 Medium
A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
CVE-2023-4623 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more 2026-10-14 7.8 High
A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f.
CVE-2023-4015 3 Debian, Linux, Redhat 4 Debian Linux, Linux Kernel, Enterprise Linux and 1 more 2026-10-14 7.8 High
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but later used. We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2.
CVE-2023-4004 5 Debian, Fedoraproject, Linux and 2 more 13 Debian Linux, Fedora, Linux Kernel and 10 more 2026-10-14 7.8 High
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.
