SUSE CVE-2026-31544

In the Linux kernel, the following vulnerability has been resolved: firmware: armscmi: Fix NULL dereference on notify error path Since commit b5daf93b809d1 "firmware: armscmi: Avoid notifier registration for unsupported events" the call chains leading to the helper scmieventhandlergetops expect a...

SUSE CVE-2026-31553

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix the descriptor address in kvmatswapdesc Using "u64 user hva + offset" to get the virtual addresses of S1/S2 descriptors looks really wrong, if offset is not zero. What we want to get for swapping is hva + offset,...

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...

DEBIAN-CVE-2026-31600

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: Handle invalid large leaf mappings correctly It has been possible for a long time to mark ptes in the linear map as invalid. This is done for secretmem, kfence, realm dma memory un/share, and others, by simply clearing...
