CVE-2026-89927

CVE-2026-89927 is an integer overflow vulnerability in the Linux kernel's KVM x86 Hyper-V synthetic timer (stimer) emulation. When the STIMER COUNT MSR is programmed with a value close to U64_MAX , the deadline calculation overflows, producing a deadline in the past. This causes the hrtimer to fi...

CVE-2026-74653

A flaw was found in the Linux kernel's 8250of serial driver, specifically affecting NXP LPC32xx UARTs. A local user could repeatedly open a specific serial port, triggering a stuck RX character-timeout interrupt. This leads to an interrupt storm that can livelock the CPU, resulting in a Denial of...
