CVE Vulnerability Catalog

The vulnerability in the Nokogiri library affects the protected copy helper used by Node#dup and #clone methods. It unwrapped the source argument as an xmlNode without a type check, causing an out-of-bounds read on xmlNs structure and process crash when a non-Node object (e.g. Namespace) was supplied. Version 1.19.4 adds a type check and raises TypeError.

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 vulnerability in the Crass library allows a DoS attack by providing a stylesheet with a very large number of adjacent CSS comments when the :preserve_comments option is disabled (default behavior). This causes excessive recursion and potential system resource exhaustion.

No description is available for CVE-2026-6502. The nature of the vulnerability cannot be determined.

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.

A segmentation fault was discovered in the libde265 library (commit d9fea9d) in the decoder_context::compute_framedrop_table() function. This vulnerability may cause crashes in applications using this library.

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.

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.

The html.Parse function in golang.org/x/net/html has quadratic parsing complexity for specially crafted HTML inputs, which can lead to denial of service (DoS).

A use-after-free vulnerability was found in the QEMU LSI53C895A SCSI Host Bus Adapter emulation. This issue can lead to a crash or VM escape.

The ORAS Go library can forward registry credentials configured for one origin to a different HTTP origin during registry redirects. This occurs when fetching manifests or metadata.

An issue was discovered in py-lmdb 0.97 where for certain values of mn_flags, mdb_cursor_set triggers a memcpy with an invalid write operation within mdb_xcursor_init1. This occurs when accessing a data.mdb file supplied by an attacker.

In the Linux kernel, the bnge driver has a vulnerability where a return statement is missing after auxiliary_device_uninit() in the error path. After auxiliary_device_add() fails, execution continues, potentially leading to use-after-free.

A vulnerability in the Nokogiri library affects the `Nokogiri::XML::NodeSet#[]` method (and its alias `#slice`). The index check against the node set's bounds used a 32-bit-truncated copy of the index, allowing a large negative index to pass the check and then be used at full width, reading outside the node set's storage.

Insufficient granularity of access control in SEV firmware allows a privileged user with a malicious hypervisor to create a SEV-ES guest with an ASID meant for SEV-SNP guests, potentially leading to partial loss of confidentiality.

The email module in Python, specifically the BytesGenerator class, improperly quotes newlines in email headers during serialization, allowing header injection. This only affects usage of LiteralHeader that does not respect email folding.

A vulnerability in the UEFI implementation within QEMU (or similar software) causes a heap overflow in the hardware module (hw/uefi). An attacker can exploit this flaw to gain unauthorized access or execute arbitrary code.

In glibc 2.15, a bug was introduced in the nscd daemon that causes a null pointer dereference when a not-found netgroup response is not added to the cache. This leads to a crash of nscd.

A vulnerability in the Nodemailer library allows header injection via the `list.*.comment` field, which is not sanitized for CR (`\r`) and LF (`\n`) characters. An attacker can supply a malicious value in this field, leading to email header spoofing.

When a client is configured with a namespace, a request that hit a transient network error (timeout or connection closed by memcached or a proxy) was retried with the namespace applied a second time, so app:x became app:app:x.
