CVE Vulnerability Catalog

libcurl accidentally skips certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks.

The curl_url_get() function in libcurl offers punycode conversions to and from IDN. When converting a name that is exactly 256 bytes, libcurl reads outside a stack-based buffer when built with the macidn IDN backend.

A vulnerability in libfuse versions 3.18.0 through 3.18.1 causes a NULL pointer dereference and memory leak in the fuse_uring_init_queue function. A local user can exploit this to crash the FUSE daemon or exhaust system resources.

In the Linux kernel, a vulnerability was found in the mechanism preventing timer interrupt starvation. Missing resets of the next_event_forced flag in several places, such as when the clock event state changes, may cause incorrect behavior.

In the Linux kernel, a vulnerability in KVM for AMD SEV-SNP was found. During SNP launch finish, the synchronization and encryption of VMSA (Virtual Machine Save Area) does not lock all vCPUs, allowing userspace to manipulate or run a vCPU while its state is being synchronized.

Security advisory GHSA-2hw4-c9m4-f2fj concerns the knative/pkg component. Verification on 2026-05-19 confirmed end-to-end amplification of 4.5×, worse than the advisory's conservative 2× claim. A Go proof of concept (cmd/poc-c2/main.go) was built.

An issue in Axios 1.5.1 inadvertently reveals the confidential XSRF-TOKEN stored in cookies by including it in the HTTP header X-XSRF-TOKEN for every request made to any host, allowing attackers to view sensitive information.

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).

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

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 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.

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.

The html.Parse function in the golang.org/x/net/html package enters an infinite loop when processing specially crafted HTML input. An attacker can exploit this vulnerability to cause a denial of service (DoS).

An improper initialization vulnerability in the AMD Secure Encrypted Virtualization (SEV) firmware allows an admin-privileged attacker to corrupt RMP-covered memory, potentially leading to loss of guest memory integrity.

The mongo-go-driver contains a heap out-of-bounds read vulnerability in the CGo implementation for GSSAPI (Kerberos) authentication on Linux and macOS. The issue arises from incorrect assumptions about string termination in the GSSAPI standard, potentially leading to data disclosure.

An improper access control vulnerability in AMD Secure Encrypted Virtualization (SEV) firmware allows a malicious hypervisor to bypass RMP protections, potentially compromising SEV-SNP guest memory integrity.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware causes insufficient or incomplete data removal in a hardware component, resulting in incomplete IOMMU flushing. This can potentially lead to a loss of confidentiality and integrity in guest memory.

In the Linux kernel, a vulnerability was found in the F2FS filesystem involving uninitialized value access in the f2fs_sanity_check_node_footer function. The issue was reported by syzbot and may lead to unpredictable system behavior.

A use-after-free vulnerability in SEV firmware allows a malicious hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent, potentially leading to loss of integrity.

In the Linux kernel, a vulnerability in the mshv_vtl component occurs when registering VTL0 memory via MSHV_ADD_VTL0_MEMORY, where the computed vmemmap_shift may exceed MAX_FOLIO_ORDER, leading to incorrect behavior.
