unbound: Unbound DNSSEC Validator Use-After-Free via Deep Copy Pointer Overwrite Leading to DoS and Possible Remote Code Execution

A flaw was discovered in Unbound’s DNSSEC validator can leave it using an invalid memory pointer after certain DS sub-query validations fail due to NSEC3 budget exhaustion. This may cause crashes and could potentially allow arbitrary code execution...

CVE-2026-9516

Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws. To skip a leading 3-byte UTF-8 BOM, decodejson advances the input scalar's string pointer past the mark with SvPVset and restores it only on the normal return...

liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. Prior to 0.16.0, an out-of-bounds read has been identified in the XMSS and XMSS^MT stateful signature verification code. When the verification function is called with a...

kernel: mm: thp: deny THP for files on anonymous inodes

A flaw was found in the Linux kernel's Transparent Huge Pages THP mechanism. This vulnerability occurs because the filethpenabled function incorrectly allows THP for files on anonymous inodes, which are not designed for this feature. An attacker could potentially exploit this by manipulating...

SUSE CVE-2022-32166

In ovs versions v0.90.0 through v2.5.0 are vulnerable to heap buffer over-read in flow.c. An unsafe comparison of “minimasks” function could lead access to an unmapped region of memory. This vulnerability is capable of crashing the software, memory modification, and possible remote execution...

Amazon Linux 2 : soci-snapshotter, --advisory ALAS2DOCKER-2026-123 (ALASDOCKER-2026-123)

The version of soci-snapshotter installed on the remote host is prior to 0.13.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2DOCKER-2026-123 advisory. When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of C...
