| In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Reject attempts to sync VMSA of an already-launched/encrypted vCPU Reject synchronizing vCPU state to its associated VMSA if the vCPU has already been launched, i.e. if the VMSA has already been encrypted. On a host with SNP enabled, accessing guest-private memory generates an RMP #PF and panics the host.

With SEV-ES, KVM would "just" clobber guest state, which is totally fine from a host kernel perspective since userspace can clobber guest state any time before sev_launch_update_vmsa(). | ||||

| In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Protect *all* of sev_mem_enc_register_region() with kvm->lock Take and hold kvm->lock for before checking sev_guest() in sev_mem_enc_register_region(), as sev_guest() isn't stable unless kvm->lock is held (or KVM can guarantee KVM_SEV_INIT{2} has completed and can't rollack state). If KVM_SEV_INIT{2} fails, KVM can end up trying to add to a not-yet-initialized sev->regions_list, e.g. triggering a #GP Oops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] CPU: 110 UID: 0 PID: 72717 Comm: syz.15.11462 Tainted: G U W O 6.16.0-smp-DEV #1 NONE Tainted: [U]=USER, [W]=WARN, [O]=OOT_MODULE Hardware name: Google, Inc.

| CVE-2026-31591 | 1 Linux | 1 Linux Kernel | 2026-04-27 | 7.0 High |
| 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 synchronized would at best corrupt vCPU state, and at worst crash the host kernel. Opportunistically assert that vcpu->mutex is held when synchronizing its VMSA (the SEV-ES path already locks vCPUs). | ||||

| CVE-2026-5201 | 2 Gnome, Redhat | 2 Gdk-pixbuf, Enterprise Linux | 2026-04-27 | 7.5 High |
| A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions. | ||||
| CVE-2026-34003 | 1 Redhat | 1 Enterprise Linux | 2026-04-27 | 7.8 High |
| A flaw was found in the X.Org X server's XKB key types request validation. A local attacker could send a specially crafted request to the X server, leading to an out-of-bounds memory access vulnerability. This could result in the disclosure of sensitive information or cause the server to crash, leading to a Denial of Service (DoS). In certain configurations, higher impact outcomes may be possible. | ||||
| CVE-2026-34001 | 1 Redhat | 1 Enterprise Linux | 2026-04-27 | 7.8 High |
| A flaw was found in the X.Org X server. This use-after-free vulnerability occurs in the XSYNC fence triggering logic, specifically within the miSyncTriggerFence() function. An attacker with access to the X11 server can exploit this without user interaction, leading to a server crash and potentially enabling memory corruption. This could result in a denial of service or further compromise of the system. | ||||
| CVE-2026-33999 | 1 Redhat | 1 Enterprise Linux | 2026-04-27 | 7.8 High |
| A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of service (DoS) or other severe impacts. | ||||

| CVE-2025-64348 | 2 Elog, Elog Project | 2 Elog, Elog | 2026-04-26 | 7.1 High |
| ELOG allows an authenticated user to modify or overwrite the configuration file, resulting in denial of service. If the execute facility is specifically enabled with the "-x" command line flag, attackers could execute OS commands on the host machine. By default, ELOG is not configured to allow shell commands or self-registration. | ||||
| CVE-2025-35051 | 1 Newforma | 2 Project Center, Project Center Server | 2026-04-26 | 9.8 Critical |
| Newforma Project Center Server (NPCS) accepts serialized .NET data via the '/ProjectCenter.rem' endpoint on 9003/tcp, allowing a remote, unauthenticated attacker to execute arbitrary code with 'NT AUTHORITY\NetworkService' privileges. According to the recommended architecture, the vulnerable NPCS endpoint is only accessible on an internal network. To mitigate this vulnerability, restrict network access to NPCS. | ||||
| CVE-2025-26793 | 2026-04-26 | N/A | ||
| The Web GUI configuration panel of Hirsch (formerly Identiv and Viscount) Enterphone MESH through 2024 ships with default credentials (username freedom, password viscount). The administrator is not prompted to change these credentials on initial configuration, and changing the credentials requires many steps. Attackers can use the credentials over the Internet via mesh.webadmin.MESHAdminServlet to gain access to dozens of Canadian and U.S. apartment buildings and obtain building residents' PII. NOTE: the Supplier's perspective is that the "vulnerable systems are not following manufacturers' recommendations to change the default password." | ||||
