CVE-2026-89963

A flaw was found in the Linux kernel's powerpc/kexecfile component. On systems configured without reserved memory regions, a NULL pointer dereference can occur in the kexecextrafdtsizeppc64 function during extra size calculation. This can lead to a kernel panic, effectively causing a denial of...

CVE-2026-93211

A flaw was found in the nfsd component of the Linux kernel. Due to an incorrect initialization order of the Dynamic Resource Cache DRC hash table, a system crash Denial of Service can occur on weakly-ordered architectures like ARM64 and PowerPC. This happens when a shrinker scan attempts to acces...

CVE-2026-98433

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for PowerPC architectures. When handling secure virtual machines, a failure during secure memory paging fails to release allocated device memory and internal metadata. A local user can exploit this vulnerability by...
