CVE-2026-14677
A flaw was found in PostgreSQL. An integer wraparound vulnerability in 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This can lead to arbitrary code execution as the operating system...
CVE-2026-64531
CVE-2026-64531 — OVSwrap PoC de escalonamento de privilégios local usuário comum → root no módulo Open vSwitch do kernel Linux. Utiliza o wraparound de inteiro do campo nlalen de 16 bits para elevar de usuário comum até root. Resumo da vulnerabilidade Quando o fluxo de actions aninhadas gerado pe...
CVE-2026-15742
A flaw was found in PostgreSQL fuzzystrmatch. A low-privileged database user can exploit an integer wraparound vulnerability by providing extreme inputs to the levenshtein or levenshteinlessequal SQL functions. This allows the user to execute arbitrary code as the operating system user running th...
CVE-2026-14662
A flaw was found in PostgreSQL. An unprivileged database user can exploit an integer wraparound vulnerability in the tsvector and tsquery data type functions. By providing crafted large inputs, the server can be forced to undersize an allocation, leading to an out-of-bounds write. This could...
EUVD-2026-65624
CAI Content Credentials is affected by an Integer Underflow Wrap or Wraparound vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue does not...
CVE-2026-50142
A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker can provide a specially crafted HEIF sequence that triggers an unbounded heap allocation. This occurs because the HEIF sequence parser's fixed-size mode is missing a bound check, and an integer...
CVE-2026-73193
A flaw was found in DBI. On 32-bit Perl systems, a vulnerability exists in the preparse function due to an integer wraparound when calculating the output buffer size. A remote attacker can exploit this by providing a specially crafted, excessively large statement. This can lead to a heap...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: ALSA: emu10k1: Fixed an out-of-bounds access in sndemu10k1pcmchannelalloc The voice allocator sometimes begins allocating from near the end of the array, and then wraps around. However, sndemu10k1pcmchannelalloc accesses the newl...

Integer overflow or wraparound in Azure Data Manager for Energy allows an authorized attacker to execute code over a network...
OESA-2026-3420 postgresql security update
PostgreSQL is an advanced Object-Relational database management system DBMS. The base postgresql package contains the client programs that you'll need to access a PostgreSQL DBMS server, as well as HTML documentation for the whole system. These client programs can be located on the same machine a...
BIT-POSTGRESQL-2026-15742 PostgreSQL fuzzystrmatch writes effectively-arbitrary addresses, via integer wraparound
Integer wraparound in PostgreSQL fuzzystrmatch allows a user to direct writes to a huge range of addresses, executing arbitrary code as the operating system user running the database, via extreme inputs to SQL function levenshtein or levenshteinlessequal. Versions before PostgreSQL 18.5, 17.11,...
BIT-POSTGRESQL-2026-14677 PostgreSQL 32-bit pltcl and plperl undersize allocations, via integer wraparound
Integer wraparound in PostgreSQL 32-bit builds of pltcl and plperl allows an object creator to cause the server to undersize an allocation and write out-of-bounds via crafted function bodies. This may execute arbitrary code as the operating system user running the database. CVE-2026-6473 had fixe...
EUVD-2026-62364
The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...
SUSE CVE-2026-73193
DBI versions before 1.652 for Perl allow a heap out-of-bounds write on 32-bit perl via an integer wraparound in the output buffer size computed by preparse. preparse reserves its output buffer with newSVstrlenstatement 7 + 16, budgeting seven output bytes per input byte for the longest ':p99999'...

CVE-2026-73193
In DBI's preparse function, buffer size is computed as strlen(statement) * 7 + 16 in a 32-bit STRLEN, wrapping at ~613 MB input to reserve only 19 bytes; a raw pointer copy then writes the entire input past the allocation. Affected: DBI
