CVE-2026-50538

LibVNCClient is a library for easy implementation of a VNC client. In versions 0.9.12 through 0.9.15, a malicious or man-in-the-middle VNC server can force a connecting libvncclient to write attacker-controlled data past the end of its framebuffer. This is an out-of-bounds heap write with...

CVE-2026-50538

LibVNCClient (part of the LibVNCServer project) versions 0.9.12 through 0.9.15 contain an out-of-bounds heap write in the Tight decoder . A malicious or man-in-the-middle VNC server can trigger this by sending a single crafted FramebufferUpdate message, writing attacker-controlled data past the e...

CVE-2026-45271 picotls has infinite recursion in the minicrypto ASN.1 decoder

Picotls is a TLS protocol library that allows users select different crypto backends based on their use case. Picotls implements its own ASN.1 validation helper, which is used by the minicrypto backend while parsing local PKCS8 private keys. Prior to commit c14231d801407640bc42c2dcf92783409ea6a7c...

CVE-2026-45271

CVE-2026-45271 affects picotls , a TLS protocol library. The minicrypto backend 's ASN.1 validation helper recursively descends into constructed ASN.1 elements without enforcing a maximum nesting depth. An attacker who can supply a crafted private-key file (via ptls_minicrypto_load_private_key())...

DEBIAN-CVE-2026-55893

Capstone is a disassembly framework. In 6.0.0-Alpha9 and earlier, Capstone's arch/SH/SHDisassembler.c SH floating-point decoders such as opFADD, opFMUL, and opFSUB call setreg and setregn using shinfo.op.opcount without checking the fixed-size operands array. Repeated crafted instructions process...

DEBIAN-CVE-2026-70653

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, the old-style Radiance RLE decoder in libvips/foreign/radiance.c can process a repeat marker at the beginning of a scanline in scanlinereadold and read q-1 before any prior pixel exists. A crafted Radiance...

CVE-2026-74274

A flaw was found in the Linux kernel's CXL Compute Express Link driver. When endpoint decoders are removed from a CXL region's target array, the driver can fail to properly fill the resulting NULL pointer holes. This can lead to the system attempting to access a NULL pointer, causing a general...

CVE-2026-55192

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can provide a specially crafted H.264 video stream that causes the client's H.264 decoder to read beyond its allocated memory. This out-of-bounds read can lead to the disclosure of sensitive client memory or cause the...
