SUSE CVE-2026-92520

In the Linux kernel, the following vulnerability has been resolved: bpf: Zero queue and stack outputs on lock failure Queue and stack pop/peek helpers accept an uninitialized output buffer because the verifier expects the helper to initialize it. The empty-map error path clears the buffer, but a...

PT-2026-96669

Name of the Vulnerable Software and Affected Versions Net::IDN::Punycode versions 2.302 through 2.589 Description An issue exists in the XS backend where the output buffer is leaked whenever a label is rejected in the decode punycode function. The XS backend allocates a scalar before validating...

CVE-2026-84444 libheif uncompressed tiled image encoding allows out-of-bounds write

libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.23.2, when WITHUNCOMPRESSEDCODEC is enabled, heifcontextaddimagetile accepts an independently constructed tile whose component-plane dimensions do not match the tile geometry established by the prototype image...

unbound: Unbound: Denial of Service via use-after-free in DoQ stream output buffer

A flaw was found in Unbound. This vulnerability occurs in the DNS-over-QUIC DoQ stream output buffer when a client sends a RESETSTREAM, causing the output buffer to be freed while retransmission entries still point to it. A remote attacker, by querying Unbound over DoQ, withholding acknowledgment...

CVE-2026-78227

NLnet Labs Unbound versions 1.22.0 through 1.26.1 contain a use-after-free vulnerability in the DNS-over-QUIC (DoQ) implementation, triggered only when compiled with '--with-libngtcp2'. The root cause is that ngtcp2's retransmission buffer retains a shallow pointer into a per-stream output buffer...

CVE-2026-78227 Use-after-free in DoQ stream output buffer on reset re-transmission

NLnet Labs Unbound 1.22.0 up to and including 1.26.1, has a use-after-free vulnerability when compiled for DNS-over-QUIC support with '--with-libngtcp2'. Each DoQ stream owns an output buffer that holds the DNS response. ngtcp2's retransmission buffer keeps a shallow pointer into the output buffe...

CVE-2026-58081

A flaw was found in iconv. Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly validate the size of the provided output buffer before writing converted characters. This oversight could allow an application using iconv to convert untrusted input with one of the affected...

Linux Distros Unpatched Vulnerability : CVE-2026-58081

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

CVE-2026-58081 Heap based buffer overflow in iconv(3)

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...
