CVE-2026-72647

CVE-2026-72647 affects Elasticsearch. Uncontrolled recursion (CWE-674) via deeply nested serialized data can cause denial of service when an authenticated user with read access on a single index submits a crafted search request; depth is not limited, exhausting the thread stack and terminating th...

CVE-2026-72647 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

Uncontrolled Recursion CWE-674 in Elasticsearch can lead to denial of service via Serialized Data with Nested Payloads CAPEC-230. An authenticated user holding only read privileges on a single index can submit one specially crafted search request whose deeply nested structure is processed without...

CVE-2026-72679 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

Elasticsearch does not apply its configurable input length restriction to a user-supplied pattern accepted by an intervals query. Compiling a deeply nested pattern drives unbounded recursion that exhausts the thread stack and raises a fatal error, terminating the Elasticsearch node process and...

CVE-2026-72686 Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single request containing a crafted user-supplied input. A specific internal component validates the input using a recursive routine and applies no bound to the length of the value being validated, so the validation...

CVE-2026-6791

A flaw was found in glibc. When processing paths that start with a tilde followed by a username, the wordexp function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhausti...

glibc: Glibc: Denial of Service via stack exhaustion during tilde expansion

A flaw was found in glibc. When processing paths that start with a tilde followed by a username, the wordexp function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhausti...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: AppArmor: The recursive profile removal method has been replaced with an iterative approach. The profile removal code uses recursion when removing nested profiles, which can lead to kernel stack exhaustion and system crashes...

Astra Linux – Vulnerability in libxml2

A flaw was identified in the RelaxNG parser of libxml2 regarding how external schema inclusions are handled. The parser does not enforce a limit on the inclusion depth when resolving nested directives. Specifically crafted or overly complex schemas can cause excessive recursion during parsing. Th...
