CVE-2026-93168

A flaw was found in the Linux kernel's dmaengine: xilinxdma component. When the xilinxdmapolltimeout function is called with a zero-value delay and an unfulfilled condition, the CPU can enter a prolonged busy-wait state. This occurs due to an underestimation of wall clock time, causing the system...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises from the fact that when calling xilinxdmapolltimeout, delayus is set to 0, and the waiting condition is never satisfied. The polltimeoutusatomic significantly underestimates the time elapsed, resulting in the CPU being idle...
