CVE-2026-20616 1 Apple 5 Ios And Ipados, Ipados, Iphone Os and 2 more 2026-04-15 8.8 High
An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, macOS Sonoma 14.8.4, macOS Tahoe 26.3, visionOS 26.3. Processing a maliciously crafted USD file may lead to unexpected app termination.
CVE-2016-8622 2 Haxx, Redhat 3 Libcurl, Jboss Core Services, Rhel Software Collections 2026-04-15 N/A
The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 17 Ubuntu Linux, Debian Linux, Libcurl and 14 more 2026-04-15 9.8 Critical
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2026-34863 1 Huawei 1 Harmonyos 2026-04-15 6.7 Medium
Out-of-bounds write vulnerability in the file system. Impact: Successful exploitation of this vulnerability may affect availability.
CVE-2026-27258 1 Adobe 2 Dng Sdk, Dng Software Development Kit 2026-04-15 5.5 Medium
DNG SDK versions 1.7.1 2502 and earlier are affected by an out-of-bounds write vulnerability that could lead to application denial-of-service. An attacker could leverage this vulnerability to corrupt memory, causing the application to crash or become unresponsive. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2026-5443 2 Orthanc, Orthanc-server 2 Dicom Server, Orthanc 2026-04-15 9.8 Critical
A heap buffer overflow vulnerability exists during the decoding of `PALETTE COLOR` DICOM images. Pixel length validation uses 32-bit multiplication for width and height calculations. If these values overflow, the validation check incorrectly succeeds, allowing the decoder to read and write to memory beyond allocated buffers.
CVE-2026-35633 1 Openclaw 1 Openclaw 2026-04-15 5.3 Medium
OpenClaw before 2026.3.22 contains an unbounded memory allocation vulnerability in remote media HTTP error handling that allows attackers to trigger excessive memory consumption. Attackers can send crafted HTTP error responses with large bodies to remote media endpoints, causing the application to allocate unbounded memory before failure handling occurs.
CVE-2026-34618 3 Adobe, Apple, Microsoft 3 Illustrator, Macos, Windows 2026-04-15 7.8 High
Illustrator versions 30.2, 29.8.5 and earlier are affected by an out-of-bounds write 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-2026-34631 3 Adobe, Apple, Microsoft 3 Incopy, Macos, Windows 2026-04-15 7.8 High
InCopy versions 20.5.2, 21.2 and earlier are affected by an out-of-bounds write 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-2026-21259 1 Microsoft 9 365 Apps, Excel, Excel 2016 and 6 more 2026-04-15 7.8 High

CVE-2026-23225 1 Linux 1 Linux Kernel 2026-04-15 7.8 High
In the Linux kernel, the following vulnerability has been resolved: sched/mmcid: Don't assume CID is CPU owned on mode switch Shinichiro reported a KASAN UAF, which is actually an out of bounds access in the MMCID management code. CPU0 CPU1 T1 runs in userspace T0: fork(T4) -> Switch to per CPU CID mode fixup() set MM_CID_TRANSIT on T1/CPU1 T4 exit() T3 exit() T2 exit() T1 exit() switch to per task mode ---> Out of bounds access. As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in the task and drops the CID, but it does not touch the per CPU storage. That's functionally correct because a CID is only owned by the CPU when the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag. Now sched_mm_cid_exit() assumes that the CID is CPU owned because the prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the not set ONCPU bit and then invokes clear_bit() with an insanely large bit number because TRANSIT is set (bit 29). Prevent that by actually validating that the CID is CPU owned in mm_drop_cid_on_cpu().
CVE-2026-2792 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-04-15 9.8 Critical
Memory safety bugs present in Firefox ESR 140.7, Thunderbird ESR 140.7, Firefox 147 and Thunderbird 147. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 148, Firefox ESR 140.8, Thunderbird 148, and Thunderbird 140.8.
