CVE Vulnerability Catalog

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 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.

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.

HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware allows a privileged attacker to modify the lock bit, potentially downgrading the firmware and compromising system integrity.

A vulnerability in the Linux kernel's FUSE filesystem causes a hang during sync initialization when the FUSE server exits (e.g., due to error or crash) while processing the FUSE_INIT request. The issue stems from the lack of abort on a fatal signal, blocking filesystem creation.

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.

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 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.

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.

HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.

Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests.

Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerable to information disclosure, SSRF or local script execution via backend applications whose response headers are malicious or exploitable.

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.

The net-tools package up to version 2.10 does not properly validate the structure of /proc files, which may lead to errors when reading data.

Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe RewriteRules to unexpectedly setup URLs to be handled by mod_proxy.

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.

W jądrze Linuxa naprawiono podatność związaną z systemem plików f2fs, która dotyczyła braku odpowiednich kontroli sanity na liczbie całkowitych ważnych bloków. Zgłoszono błąd f2fs, który prowadził do awarii jądra.

W jądrze Linuxa zidentyfikowano podatność związaną z funkcją hdr_first_de(), która może zwracać wskaźnik NULL. Niezbędne jest wdrożenie odpowiedniego mechanizmu obsługi błędów dla tej funkcji.

W jądrze Linuxa rozwiązano podatność związaną z używaniem funkcji strlcat() w sterowniku lpfc, która powodowała panikę systemu z powodu błędnego wykrywania przepełnienia bufora. Zamiast tego, zastosowano funkcję memcpy() dla wersji BIOS.
