CVE-2026-31553

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine component. Specifically, in the ARM64 architecture, an incorrect calculation of the descriptor address in the kvmatswapdesc function could lead to memory corruption. This vulnerability may allow an attacker to cause system...

CVE-2026-31544

A flaw was found in the Linux kernel's armscmi firmware component. The scmieventhandlergetops helper function can return a NULL pointer when an event handler is not found or created, instead of an expected error pointer. This improper handling of the error path leads to a NULL dereference...
