CVE-2026-8956 1 Mozilla 2 Firefox, Thunderbird 2026-05-20 9.8 Critical
Integer overflow in the Networking: JAR component. This vulnerability was fixed in Firefox 151, Firefox ESR 140.11, Thunderbird 151, and Thunderbird 140.11.
CVE-2026-32738 1 Struktur 1 Libheif 2026-05-20 6.5 Medium
libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 792-byte HEIF sequence file with samples_per_chunk=0 in the stsc box causes an unsigned integer underflow in the Chunk constructor (m_last_sample = 0 + 0 - 1 = UINT32_MAX), mapping all samples to an empty chunk and resulting in a denial of service. When any sample is accessed, the library reads from index 0 of an empty std::vector, causing a guaranteed SEGV (null-page read). The file parses successfully without producing an error; the crash occurs on the first frame access. This issue has been fixed in version 1.22.0.
CVE-2026-8954 1 Mozilla 2 Firefox, Thunderbird 2026-05-19 7.5 High
Incorrect boundary conditions, integer overflow in the Audio/Video component. This vulnerability was fixed in Firefox 151, Firefox ESR 140.11, Thunderbird 151, and Thunderbird 140.11.

Integer overflow in Skia in Google Chrome on Windows prior to 148.0.7778.168 allowed a remote attacker who had compromised the renderer process to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)
CVE-2026-8519 2 Google, Microsoft 2 Chrome, Windows 2026-05-19 8.8 High
Integer overflow in ANGLE in Google Chrome on Windows prior to 148.0.7778.168 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)
CVE-2026-8534 2 Google, Linux 3 Chrome, Chrome Os, Linux Kernel 2026-05-19 8.3 High
Integer overflow in GPU in Google Chrome on Linux and ChromeOS prior to 148.0.7778.168 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
CVE-2026-8577 1 Google 1 Chrome 2026-05-19 8.8 High
Integer overflow in Fonts in Google Chrome prior to 148.0.7778.168 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-8559 2 Google, Microsoft 2 Chrome, Windows 2026-05-19 4.3 Medium
Integer overflow in Internationalization in Google Chrome on Windows prior to 148.0.7778.168 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: High)
CVE-2026-27781 1 Openharmony 1 Openharmony 2026-05-19 3.3 Low
in OpenHarmony v6.0 and prior versions allow a local attacker cause DOS.
CVE-2026-32849 1 Netbsd 1 Src 2026-05-19 5.5 Medium
NetBSD prior to commit ec8451e contains a signed integer overflow vulnerability in the cryptodev_op() function in sys/opencrypto/cryptodev.c where the local variable iov_len is declared as a signed int but assigned from an unsigned cop->dst_len value, causing undefined behavior when cop->dst_len exceeds INT_MAX. A local attacker with access to /dev/crypto and a compression session type can exploit this vulnerability by providing a dst_len value exceeding INT_MAX to trigger a kernel panic through NULL pointer dereference when CONFIG_SVS is disabled and corrupted UIO pointer arithmetic.
CVE-2026-8532 1 Google 1 Chrome 2026-05-19 8.8 High
Integer overflow in XML in Google Chrome prior to 148.0.7778.168 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
CVE-2026-42371 1 Uriparser Project 1 Uriparser 2026-05-18 5.1 Medium
uriparser before 1.0.1 has numeric truncation in text range comparison, if an application accepts URIs with a length in gigabytes.
CVE-2026-6473 2 Postgresql, Redhat 2 Postgresql, Hummingbird 2026-05-18 8.8 High
Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.
CVE-2026-42580 2 Io.netty, Netty 2 Netty-codec-http, Netty 2026-05-18 6.5 Medium
Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's chunk size parser silently overflows int, enabling request smuggling attacks. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
CVE-2026-44216 1 Bytecodealliance 1 Wasmtime 2026-05-18 7.5 High
Wasmtime is a runtime for WebAssembly. From 30.0.0 to 36.0.8, 43.0.2, and 44.0.1, Wasmtime's allocation logic for a WebAssembly table contained checked arithmetic which panicked on overflow. This overflow is possible to trigger, and thus panic, when a table with an extremely large size is allocated. This is possible with the WebAssembly memory64 proposal where tables can have sizes in the 64-bit range as opposed to the previous 32-bit range which would not overflow. The panic happens when attempting to create a very large table, such as when instantiating a WebAssembly module or component. This vulnerability is fixed in 36.0.8, 43.0.2, and 44.0.1.
CVE-2026-43909 2 Academysoftwarefoundation, Openimageio 2 Openimageio, Openimageio 2026-05-17 8.8 High
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed 32-bit integer overflow in the loop index expression i * 4 inside SwapRGBABytes() causes the function to compute a large negative pointer offset when processing kABGR DPX images with large dimensions. The immediate crash is an out-of-bounds read (the memcpy at line 45 reads from &input[i * 4] first), but the subsequent write operations at lines 46–49 target the same wrapped offset — making this a combined OOB read+write primitive. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.
