CVE-2026-39316 1 Openprinting 1 Cups 2026-04-16 4 Medium
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted. cupsdDeleteTemporaryPrinters() in scheduler/printers.c calls cupsdDeletePrinter() without first expiring subscriptions that reference the printer, leaving cupsd_subscription_t.dest as a dangling pointer to freed heap memory. The dangling pointer is subsequently dereferenced at multiple code sites, causing a crash (denial of service) of the cupsd daemon. With heap grooming, this can be leveraged for code execution.
CVE-2026-25556 1 Artifex 1 Mupdf 2026-04-16 7.5 High
MuPDF versions 1.23.0 through 1.27.0 contain a double-free vulnerability in fz_fill_pixmap_from_display_list() when an exception occurs during display list rendering. The function accepts a caller-owned fz_pixmap pointer but incorrectly drops the pixmap in its error handling path before rethrowing the exception. Callers (including the barcode decoding path in fz_decode_barcode_from_display_list) also drop the same pixmap in cleanup, resulting in a double-free that can corrupt the heap and crash the process. This issue affects applications that enable and use MuPDF barcode decoding and can be triggered by processing crafted input that causes a rendering-time error while decoding barcodes.
CVE-2026-34763 1 Rack 1 Rack 2026-04-16 5.3 Medium
Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Directory interpolates the configured root path directly into a regular expression when deriving the displayed directory path. If root contains regex metacharacters such as +, *, or ., the prefix stripping can fail and the generated directory listing may expose the full filesystem path in the HTML output. This issue has been patched in versions 2.2.23, 3.1.21, and 3.2.6.
CVE-2026-5883 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-16 8.8 High
Use after free in Media in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-26983 1 Imagemagick 1 Imagemagick 2026-04-16 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, the MSL interpreter crashes when processing a invalid `<map>` element that causes it to use an image after it has been freed. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
CVE-2026-27283 3 Adobe, Apple, Microsoft 4 Indesign, Indesign Desktop, Macos and 1 more 2026-04-16 7.8 High
InDesign Desktop versions 20.5.2, 21.2 and earlier are 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-2019-5481 7 Debian, Fedoraproject, Haxx and 4 more 15 Debian Linux, Fedora, Curl and 12 more 2026-04-16 9.8 Critical
Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.
CVE-2026-20442 2 Google, Mediatek 47 Android, Mt6739, Mt6761 and 44 more 2026-04-16 4.4 Medium
In display, there is a possible system crash due to use after free. This could lead to local denial of service if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10436998; Issue ID: MSV-5723.
CVE-2026-20443 2 Google, Mediatek 47 Android, Mt6739, Mt6761 and 44 more 2026-04-16 6.7 Medium
In display, there is a possible memory corruption due to use after free. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10436998; Issue ID: MSV-5722.

CVE-2018-16840 3 Canonical, Haxx, Redhat 3 Ubuntu Linux, Curl, Jboss Core Services 2026-04-16 9.8 Critical
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
CVE-2016-8623 2 Haxx, Redhat 3 Curl, Jboss Core Services, Rhel Software Collections 2026-04-16 N/A
A flaw was found in curl before version 7.51.0. The way curl handles cookies permits other threads to trigger a use-after-free leading to information disclosure.
CVE-2026-23231 1 Linux 1 Linux Kernel 2026-04-16 7.8 High
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix use-after-free in nf_tables_addchain() nf_tables_addchain() publishes the chain to table->chains via list_add_tail_rcu() (in nft_chain_add()) before registering hooks. If nf_tables_register_hook() then fails, the error path calls nft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy() with no RCU grace period in between. This creates two use-after-free conditions: 1) Control-plane: nf_tables_dump_chains() traverses table->chains under rcu_read_lock(). A concurrent dump can still be walking the chain when the error path frees it. 2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly installs the IPv4 hook before IPv6 registration fails. Packets entering nft_do_chain() via the transient IPv4 hook can still be dereferencing chain->blob_gen_X when the error path frees the chain. Add synchronize_rcu() between nft_chain_del() and the chain destroy so that all RCU readers -- both dump threads and in-flight packet evaluation -- have finished before the chain is freed.
CVE-2026-28537 1 Huawei 1 Harmonyos 2026-04-16 5.1 Medium
Double free vulnerability in the window module. Impact: Successful exploitation of this vulnerability may affect availability.
