In the Linux kernel, the following vulnerability has been resolved: spi: topcliff-pch: fix use-after-free on unbind Give the driver a chance to flush its queue before releasing the DMA buffers on driver unbind...

CVE-2026-46274

A flaw was found in the Linux kernel's input/output work queue io-wq component. This vulnerability occurs because the system incorrectly handles work queue entries, leading to a stale pointer. A local attacker could exploit this issue by manipulating work queue operations. Successful exploitation...
