CVE-2026-2394 1 Rti 1 Connext Professional 2026-04-15 6.5 Medium
Buffer Over-read vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers.This issue affects Connext Professional: from 7.4.0 before 7.7.0, from 7.0.0 before 7.3.1.1, from 6.1.0 before 6.1.*, from 6.0.0 before 6.0.*, from 5.3.0 before 5.3.*, from 4.3x before 5.2.*.
CVE-2024-31082 1 Redhat 1 Enterprise Linux 2026-04-15 7.3 High
A heap-based buffer over-read vulnerability was found in the X.org server's ProcAppleDRICreatePixmap() function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a different endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory values and then transmit them back to the client until encountering an unmapped page, resulting in a crash. Despite the attacker's inability to control the specific memory copied into the replies, the small length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds reads.

CVE-2024-12011 2026-04-15 7.6 High
A CWE-126 “Buffer Over-read” was discovered affecting the 130.8005 TCP/IP Gateway running firmware version 12h. The information disclosure can be triggered by leveraging a memory leak affecting the web server. A remote unauthenticated attacker can exploit this vulnerability in order to leak valid authentication tokens from the process memory associated to users currently logged to the system and bypass the authentication mechanism.
CVE-2025-32052 1 Redhat 2 Enterprise Linux, Rhel Eus 2026-04-15 6.5 Medium
A flaw was found in libsoup. A vulnerability in the sniff_unknown() function may lead to heap buffer over-read.
CVE-2025-7745 2026-04-15 5.8 Medium
Buffer Over-read vulnerability in ABB AC500 V2.This issue affects AC500 V2: through 2.5.2.
CVE-2024-27280 2 Redhat, Ruby-lang 2 Enterprise Linux, Ruby 2026-04-15 9.8 Critical
A buffer-overread issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and 3.1.x through 3.1.4. The ungetbyte and ungetc methods on a StringIO can read past the end of a string, and a subsequent call to StringIO.gets may return the memory value. 3.0.3 is the main fixed version; however, for Ruby 3.0 users, a fixed version is stringio 3.0.1.1, and for Ruby 3.1 users, a fixed version is stringio 3.0.1.2.
CVE-2025-11961 1 Tcpdump 1 Libpcap 2026-04-15 1.9 Low
pcap_ether_aton() is an auxiliary function in libpcap, it takes a string argument and returns a fixed-size allocated buffer. The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented. If an application calls the function with an argument that deviates from the expected format, the function can read data beyond the end of the provided string and write data beyond the end of the allocated buffer.
CVE-2025-36855 1 Microsoft 1 .net 2026-04-15 8.8 High
A vulnerability ( CVE-2025-21176 https://www.cve.org/CVERecord ) exists in DiaSymReader.dll due to buffer over-read. Per CWE-126: Buffer Over-read https://cwe.mitre.org/data/definitions/126.html , Buffer Over-read is when a product reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer. This issue affects EOL ASP.NET 6.0.0 <= 6.0.36 as represented in this CVE, as well as 8.0.0 <= 8.0.11 & <= 9.0.0 as represented in CVE-2025-21176. Additionally, if you've deployed self-contained applications https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd  targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed. NOTE: This CVE affects only End Of Life (EOL) software components. The vendor, Microsoft, has indicated there will be no future updates nor support provided upon inquiry.
CVE-2025-4207 1 Postgresql 1 Postgresql 2026-04-15 5.9 Medium
Buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to achieve temporary denial of service on platforms where a 1-byte over-read can elicit process termination. This affects the database server and also libpq. Versions before PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 are affected.

CVE-2025-32053 1 Redhat 2 Enterprise Linux, Rhel Eus 2026-04-15 6.5 Medium
A flaw was found in libsoup. A vulnerability in sniff_feed_or_html() and skip_insignificant_space() functions may lead to a heap buffer over-read.
CVE-2024-57970 1 Redhat 1 Enterprise Linux 2026-04-15 4 Medium
libarchive through 3.7.7 has a heap-based buffer over-read in header_gnu_longlink in archive_read_support_format_tar.c via a TAR archive because it mishandles truncation in the middle of a GNU long linkname.
CVE-2024-12975 2026-04-15 N/A
A buffer overread can occur in the CPC application when operating in full duplex SPI upon receiving an invalid packet over the SPI interface.
CVE-2026-4371 1 Mozilla 1 Thunderbird 2026-04-14 7.4 High
A malicious mail server could send malformed strings with negative lengths, causing the parser to read memory outside the buffer. If a mail server or connection to a mail server were compromised, an attacker could cause the parser to malfunction, potentially crashing Thunderbird or leaking sensitive data. This vulnerability was fixed in Thunderbird 149 and Thunderbird 140.9.
CVE-2026-5772 1 Wolfssl 1 Wolfssl 2026-04-13 N/A
A 1-byte stack buffer over-read was identified in the MatchDomainName function (src/internal.c) during wildcard hostname validation when the LEFT_MOST_WILDCARD_ONLY flag is active. If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash.
