Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: microcode_ctl (UTSA-2026-110881)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-110881 advisory. Improper handling of overlap between protected memory ranges for some IntelR XeonR 6 processors when using IntelR TDX within SMM may allow an escalation of privilege...

kernel: microcode_ctl: Intel Xeon 6 Processors: Privilege escalation via improper memory range handling in SMM

A flaw was found in IntelR XeonR 6 processors when using IntelR TDX within System Management Mode SMM. Improper handling of overlap between protected memory ranges may allow a local attacker with privileged user access to escalate privileges. This vulnerability could lead to high impact on...

New DDRop Attack Breaks Intel TDX and AMD SEV-SNP Confidential Computing

Researchers have disclosed a new hardware attack, called DDRop , that breaks the memory protection in Intel and AMD confidential computing by silently dropping writes to a server's memory, so the processor keeps reading old encrypted data as if it were current. The attack requires an attacker who...

Astra Linux – Vulnerability in Intel Microcode

Improper input validation in some IntelR TDX module software prior to version 1.5.05.46.698 may allow a privileged user to potentially enable privilege escalation through local access...

Linux Distros Unpatched Vulnerability : CVE-2026-89751

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - x86/tdx: Fix off-by-one in port I/O handling handlein and handleout in arch/x86/coco/tdx/tdx.c use: u64 mask = GENMASKBITSPERBYTE size, 0 %NASLMINLEVEL 80900 C...

CVE-2026-89751

A flaw was found in the Linux kernel's x86/tdx component. An off-by-one error in the handlein and handleout functions, specifically in the GENMASK calculation for port I/O operations, causes the mask to be one bit too wide. This incorrect handling of I/O sizes could potentially lead to unintended...

CVE-2026-89751

CVE-2026-89751 is an off-by-one error in the Linux kernel's x86 TDX (Trusted Domain Extensions) port I/O handling. The functions handle_in() and handle_out() in arch/x86/coco/tdx/tdx.c compute a bitmask using GENMASK(BITS_PER_BYTE * size, 0). Since GENMASK(h, l) includes bit h , this produces a m...
