Astra Linux – vulnerability in linux-6.12

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear the Present bit prior to tearing down a context entry When tearing down a context entry, the current implementation zeros the entire 128-bit entry using multiple 64-bit writes. This creates a window during which...

CVE-2026-90243

A flaw was found in the Linux kernel's IOMMU/VT-d subsystem. During the tear-down of copied context entries, the kernel zeroes out parts of an entry before clearing its "Present" bit and invalidating related caches. This timing issue allows hardware to fetch a partially cleared entry that is stil...

CVE-2026-88775

CVE-2026-88775 is a memory overflow vulnerability affecting Citrix NetScaler ADC and Citrix NetScaler Gateway . The flaw leads to unpredictable behavior or a Denial of Service (DoS) . It specifically impacts systems configured as a Gateway (including SSL VPN, ICA Proxy, CVPN, and RDP Proxy) or as...

kernel: iommu/vt-d: Clear Present bit before tearing down PASID entry

A flaw was found in the Linux kernel's Intel VT-d Virtualization Technology for Directed I/O Scalable Mode. When a Process Address Space ID PASID table entry is being removed, the system may attempt to clear the entry before properly signaling to the hardware that the entry is no longer active...

Linux Kernel Security Vulnerabilities

The Linux kernel versions 6.8.2 to 6.9 contain security vulnerabilities. These vulnerabilities stem from the failure to clear the Present bit before removing the extensible mode context entries. This can lead to entries with hardware acquisition tearing and access to released memory, resulting in...

CVE-2026-64435

A flaw was found in the Linux kernel's auditing subsystem. Multiple readers could access the auditqueue length qlen concurrently with a writer without proper synchronization, leading to a data race. This race condition could result in inconsistent data reads, potentially causing unpredictable...

CVE-2026-64077

A flaw was found in the Linux kernel's netfilter ebtables component. A concurrency issue exists during the two-stage removal scheme where the table-ops assignment could expose a partially-filled table structure if the ebt mutex is not held. This could lead to unpredictable system behavior...

CVE-2026-8452

CVE-2026-8452 is a heap overflow in NetScaler ADC/Gateway memory handling (CWE-119), exploitable unauthenticated to crash or take control of appliances configured as Gateways or AAA servers. A public PoC achieves pre-auth RCE on version 13.1-30.52. Affected: 14.1 before 14.1-72.61 and 13.1 before...
