CVE Vulnerability Catalog

In the Linux kernel, a page fault occurs in the vfio/xe driver when resetting VF devices that do not support migration. The fix reorganizes initialization to decouple migration from reset.

A buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to cause temporary denial of service on platforms where a 1-byte over-read leads to process termination. This affects the database server and libpq.

Missing checks in certain functions related to RMP initialization allow a local admin privileged attacker to cause misidentification of I/O memory, potentially resulting in a loss of guest memory integrity.

The urllib.parse.urlsplit() and urlparse() functions in Python improperly validate bracketed hosts (`[]`), accepting hosts that are not IPv6 or IPvFuture. This violates RFC 3986 and could enable SSRF attacks if a URL is processed by multiple URL parsers.

Vulnerability in the iscsi-initiator-utils package involves out-of-bounds write and information disclosure via unvalidated IPv6 payload length. Crafted ICMPv6 Echo requests can cause the iscsiuio daemon to trust an inflated ipv6_plen larger than the actual received payload.

An improper access control vulnerability in Secure Encrypted Virtualization (SEV) allows a privileged attacker to write to the reverse map page (RMP) during Secure Nested Paging (SNP) initialization, potentially leading to loss of guest memory confidentiality and integrity.

The vulnerability in IOMMU stems from improper input validation, allowing a malicious hypervisor to reconfigure IOMMU registers. This results in loss of guest data integrity.

A medium severity vulnerability in CPython where regular expressions allow excessive backtracking during tarfile.TarFile header parsing, leading to ReDoS via specially crafted tar archives.

A high severity vulnerability in the CPython zipfile module affecting zipfile.Path. When iterating over entry names in a zip archive (e.g., namelist(), iterdir()), unexpected behavior may occur. The more common zipfile.ZipFile class is unaffected.

In CPython, the venv module and CLI do not properly quote paths when creating a virtual environment, allowing injection of commands into activation scripts (e.g., source venv/bin/activate). This enables arbitrary code execution upon activation.

The Diffie-Hellman Key Agreement Protocol allows long exponents, making certain calculations unnecessarily expensive. The 1996 van Oorschot and Wiener paper showed that appropriately short exponents can be used with adequate subgroup constraints, but these are not utilized.

A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This may allow an attacker to trigger memory allocation failures, causing a segmentation fault and application crash.

In libxml2 before 2.11.0, xmlXIncludeAddNode in xinclude.c has a use-after-free vulnerability.

In libxml2 before 2.12.10 and 2.13.6, a use-after-free exists in xmlSchemaIDCFillNodeTables and xmlSchemaBubbleIDCNodeTables in xmlschemas.c. Exploitation requires validation of a crafted XML document against an XML schema with identity constraints or a crafted schema.

CoreDNS before version 1.14.0 has a vulnerability in gRPC, HTTPS, and HTTP/3 server implementations that lack critical resource-limiting controls. An unauthenticated remote attacker can exhaust memory and degrade or crash the server by opening many concurrent connections.

There is a possible cross-site scripting vulnerability in rails-html-sanitizer when the sanitizer is configured to allow an SVG reference element such as <use>. This is related to GHSA-9wjq-cp2p-hrgf in Loofah, whose SVG local-reference logic rails-html-sanitizer mirrors.

Loofah's HTML5 sanitizer restricted only the xlink:href attribute on certain SVG elements to local, same-document references. Browsers also accept a plain href attribute as an alternative to the deprecated xlink:href per the SVG 2 spec, but Loofah did not apply the same restriction to it.

In PHP versions 8.1.x before 8.1.31, 8.2.x before 8.2.26, 8.3.x before 8.3.14, uncontrolled long string inputs to the ldap_escape() function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write.

In PHP versions 8.3.x before 8.3.19 and 8.4.x before 8.4.5, a code sequence involving the __set handler or ??= operator and exceptions can lead to a use-after-free vulnerability.

In PHP versions 8.1.x before 8.1.31, 8.2.x before 8.2.26, 8.3.x before 8.3.14, when using streams with a configured proxy and the request_fulluri option, the URI is not properly sanitized, which can lead to HTTP request smuggling and allow the attacker to perform arbitrary HTTP requests through the proxy.
