Technical description

Heap-based buffer overflow for the Intel(R) Open Volume Kernel Library (Intel(R) Open VKL) library maintained by intel(R) before version 2.0.2 within Ring 3: User Applications may allow a denial of service. System software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

CVE-2026-1202087.5 HIG

——0libheif 1.18.0 before 1.23.3 contains a heap-based buffer overflow vulnerability in unc_decoder_mixed_interleave::processTile() that allows attackers to write out of bounds by supplying chroma components with unequal bit depths. Attackers can craft a HEIF file declaring, for example, 16-bit Cb and 8-bit Cr to trigger file-controlled heap writes past the Cr plane, potentially achieving code execution in image-processing pipelines.2d CVE-2026-102212—

——0Heap-based buffer overflow in Opengear IM72XX, CM71XX, and ACM70XX firmware versions 4.8.0 through 5.5.2 on console server appliances allows an unauthenticated remote attacker to crash the index.cgi process via a crafted multipart/form-data POST request containing an overlong Content-Disposition name field.2d CVE-2026-1197276.5 MED

——5A flaw was found in GStreamer's gst-plugins-bad H.265 video parser. When parsing a specially crafted H.265 bitstream containing a Screen Content Coding (SCC) extension with certain palette predictor initializer settings, an integer underflow in the upper-bound computation allows the parser to accept an out-of-range value for the number of palette predictor entries. This causes the parser to write beyond the end of a fixed-size array, resulting in memory corruption and an application crash. Successful exploitation requires an attacker to provide a malformed H.265 media file to a vulnerable application, and is limited to a denial-of-service impact.3d CVE-2026-1101335.8 MED

——4A flaw was found in Ghostscript. When processing a specially crafted TrueType font or document embedding one, an accounting error during font rendering can bypass buffer size checks, triggering a heap-based buffer overflow. A remote attacker could exploit this by enticing a victim or automated service to open the malicious content, potentially resulting in a Denial of Service (DoS) crash or arbitrary code execution.3d CVE-2026-95367.5 HIG

——7A heap-based buffer overflow vulnerability exists in the vtkWindBladeReader FindVariableOffsets functionality of vtk (version(s): 9.6.1). A specially crafted .wind can lead to a buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.3d CVE-2026-961998.8 HIG
