PT-2026-35269

Name of the Vulnerable Software and Affected Versions Intina47 context-sync versions prior to 2.0.0 Description A flaw in the Git Integration component, specifically within the src/git-integration.ts file, allows for remote OS command injection. This occurs when an attacker sends specially crafte...

SUSE CVE-2026-31591

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Lock all vCPUs when synchronzing VMSAs for SNP launch finish Lock all vCPUs when synchronizing and encrypting VMSAs for SNP guests, as allowing userspace to manipulate and/or run a vCPU while its state is being...

CVE-2026-31541

A flaw was found in the Linux kernel. When a tracing instance with the copytracemarker option is enabled and subsequently deleted, a critical synchronization step is bypassed. This can lead to a Use-After-Free UAF vulnerability, which may allow a local attacker to corrupt memory, potentially...

CVE-2026-31593

CVE-2026-31593 is a Linux kernel KVM SEV SNP issue. The vulnerability arises when updating an already-launched and encrypted vCPU state: attempting to sync the vCPU's VMSA can trigger an SEV-SNP cryptographic memory protection (RMP) violation, causing a host panic/DoS. Technical details across mu...
