In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: check INITFAILED before nvmetrequninit in digest error path In nvmettcptryrecvddgst, when a data digest mismatch is detected, nvmetrequninit is called unconditionally. However, if the command arrived via the...

CVE-2026-64418

A flaw was found in the Linux kernel's memory management mm shrinker subsystem. A race condition exists where the shrinkerinfo array can be prematurely freed while still accessible, leading to a use-after-free or double-free vulnerability. This memory corruption can be exploited by a local attack...

CVE-2026-64290

A flaw was found in the Linux kernel's iommufd component. When a copytouser operation fails within the iommufdfaultfopsread function, the system enters an infinite loop. This continuous retry consumes 100% of the CPU and holds a mutex, which can lead to a denial of service DoS for affected system...

CVE-2026-64342

A flaw was found in the Linux kernel's USB iowarrior driver. This vulnerability, a use-after-free, occurs because write operations are not properly halted when a device disconnects. An attacker could potentially exploit this to cause system instability or execute arbitrary code...

CVE-2026-64384

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies.
