Linux kernel IPMI DoS

The vulnerability in the handleflags function within drivers/char/ipmi/ipmisiintf.c of the Linux kernel’s character-IPMI driver is related to unrestricted and uncontrolled resource allocation. Exploitation of this vulnerability may allow a remote attacker to cause a denial of service...

CVE-2026-96812

A vulnerability in Google gVisor on Linux platforms (prior to commit 573a9e73cf844f) allows a local attacker with container image deployment privileges to achieve root code execution on the host system. The issue stems from an improper exposure of resource in the host file helper (gofer ) when CU...

CVE-2026-96812 Host Root Sandbox Escape in gVisor via Character Device Passthrough and CUSE

Improper Exposure of Resource to Wrong Sphere in the host file helper gofer in Google gVisor prior to commit 573a9e73cf844f on Linux platforms with CUSE enabled allows a local attacker with container image deployment privileges to achieve root code execution on the host system. By including a...

USN-8801-1 linux-azure-fde, linux-azure-fde-7.0 vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...
