A heap-based buffer overflow flaw was found in rpm. RPMTAG_FILESIGNATURES in a crafted, unsigned RPM package's main header is declared with the wrong header type, causing hex2binv() to allocate a one-byte buffer and then write the tag's attacker-controlled, hex-decoded content — of attacker-chosen length — past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.

——5Buffer overflow in WebRTC in Google Chrome prior to 154.0.8037.97 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)2dCVE-2026-83632—29.4%
——9Allocation of resources without limits or throttling, Integer overflow or wraparound, Heap-based buffer overflow vulnerability in Apache Thrift.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.3dCVE-2026-91135—37.7%
——11Heap-based buffer overflow vulnerability in Apache Thrift C++ THeaderTransport.
When an application enables the ZLIB transform for the frames it sends, THeaderTransport::transform() copies the compressed frame into the write buffer without making sure it fits. Data that does not compress, such as content a remote peer supplied, grows under compression, so the copy writes past the end of the heap buffer by an amount that grows with the size of the frame, and for large frames it also reads past the end of the transform buffer.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.3dCVE-2026-143168.1 ALT11.0%
——3The revoked-key error path builds a human-readable failure reason using sprintf() into a heap buffer. The allocated buffer is too small for the final formatted message. When sprintf() writes the full message, it can write past the end of the heap allocation.4dCVE-2026-101283—18.6%
——6iperf3 3.20–3.21 (esnet/iperf) has a pre-auth heap buffer overflow in decrypt_rsa_message(): a 256-byte RSA buffer is BIO_read with the attacker-controlled ciphertext length (guard warns only), so an unauthenticated client overflows the heap via an oversized authtoken; fixed in 3.224dCVE-2026-1023319.6 CRÍ35.0%
