CVE-2026-103242

A heap-based buffer overflow flaw was found in rpm. RPMTAGFILESIGNATURES 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...

CVE-2026-103242

A heap-based buffer overflow exists in rpm due to a mistyped RPMTAG_FILESIGNATURES header tag in a crafted, unsigned RPM package. The flaw occurs in the hex2binv() function, which incorrectly allocates a one-byte buffer and subsequently writes attacker-controlled, hex-decoded content of arbitrary...

CVE-2026-92368

Prior versions of TeamViewer Full Client and Host for Linux and macOS (before 15.82) are vulnerable to a heap-based buffer overflow during the processing of .tvs session recording files . The flaw is caused by a size mismatch during the decompression of recorded session data, which can lead to ou...

CVE-2026-102566

CTranslate2 before 4.8.1 contains a heap-based buffer overflow in the binary model loader that fails to validate payload length against allocated buffer size. Attackers can craft malicious model files with oversized payload lengths to write past heap allocation boundaries, causing crashes or...

CVE-2026-95389

A flaw was found in the SCTP protocol dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a heap-based buffer overflow, resulting in a denial of service or potentially allowing code execution. Mitigation If the SCTP protocol...

CVE-2026-97427

A flaw was found in the Linux kernel's AMD GPU power management driver. A local user with write access to the powerplay sysfs interface could trigger a heap-based buffer overflow by providing input data exceeding the allocated buffer size. This issue can lead to memory corruption, resulting in a...

CVE-2026-95520

A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAGLONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext that shrinks a buffer allocation to one byte, after which the payload's...

CVE-2026-96423

A flaw was found in Wireshark. A heap-based buffer overflow in the X11 protocol dissector allows an attacker to cause a Denial of Service DoS by injecting malformed packets or providing a crafted capture file. Successful exploitation leads to an application crash, disrupting network packet...
