CVE-2026-63633: Heap-based Buffer Overflow

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, freerdpdspdecodeopus in libfreerdp/codec/dsp.c calls StreamEnsureRemainingCapacity on context-common.buffer even though opusdecode writes decoded PCM into the caller-supplied out stream. A malicious RDP server that...

CVE-2026-19508: Improper Restriction of Operations within the Bounds of a Memory Buffer

Heap-based buffer overflow in the multipart form-data parser in jstpost.c in RDK-B WebUI rdkb-2025q4-kirkstone.04.10.26 allows a remote unauthenticated attacker to cause memory corruption and denial of service, and potentially execute arbitrary code, via a crafted multipart/form-data request...

CVE-2026-75619: Heap-based Buffer Overflow

Tapo C100/C101 V5 contains a heap-based buffer overflow vulnerability in the RTSP service. An authenticated attacker on the local network can send specially crafted RTSP frame data containing oversized length values, resulting in out-of-bounds heap writes. Successful exploitation can crash the RT...

CVE-2026-49430: Heap-based Buffer Overflow

The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...

CVE-2026-58081: Heap-based Buffer Overflow

Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly check the size of the caller-supplied output buffer before writing converted characters. An application that uses iconv3 to convert untrusted input to or from one of the affected encodings may be vulnerable to buffer...
