CVE-2026-70646 aiosend: Deserialization of request body before signature verification (Pre-auth DoS) in webhook handler

aiosend is a synchronous and asynchronous Crypto Pay API client. Pror to version 3.0.7, WebhookHandler.feedupdate deserializes the entire request body before verifying the HMAC signature. This allows an unauthenticated attacker to force expensive parsing of arbitrary JSON payloads that will...

CVE-2026-71190

A flaw was found in OpenStack Swift's proxy server. The Accept header parser uses a regular expression that is vulnerable to catastrophic backtracking. An unauthenticated attacker can send a crafted Accept header with a small number of backslash characters in an unterminated quoted string, causin...

UBUNTU-CVE-2026-64590

In the Linux kernel, the following vulnerability has been resolved: dma-buf/udmabuf: skip redundant cpu sync to fix cacheline EEXIST warning When CONFIGDMAAPIDEBUGSG is enabled, importing a udmabuf into a DRM driver e.g. amdgpu for video playback in GNOME Videos / Showtime triggers a spurious...

CVE-2026-64604

CVE-2026-64604 concerns the Linux kernel KVM VMX path, where CR8 intercept updates are performed: the VMCS12 state is grabbed only when the vCPU is in guest mode to avoid a lockdep assertion in get_vmcs12(). The provided description and call trace show that the issue arises during vCPU creation a...

EUVD-2026-53790

In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Grab vmcs12 on CR8 interception update iff vCPU is in guest mode When updating CR8 intercepts, get vmcs12 if and only if the vCPU is in guest mode so that a future change can have update CR8 intercepts during vCPU...

CVE-2026-64590

The CVE-2026-64590 entry concerns the Linux kernel dma-buf/udmabuf path where, with CONFIG_DMA_API_DEBUG_SG enabled, importing udmabuf into a DRM driver (e.g., amdgpu) could emit a spurious cacheline EEXIST warning due to overlapping per-page SG mappings. The fix is to pass DMA_ATTR_SKIP_CPU_SYNC...
