CVE-2026-89604

A flaw was found in the Linux kernel's efivarfs component. An unprivileged local user can exploit this by repeatedly calling the statfs handler on the efivarfs mount point. This action triggers a flood of calls to the QueryVariableInfo runtime service, which is particularly costly on x86 systems...

CVE-2022-48769

In CVE-2022-48769, the Linux kernel vulnerability concerns Apple x86 EFI runtime services. The issue stems from a call to QueryVariableInfo() (added with EFI 2.00) used at runtime, which could crash firmware on certain Apple machines when managing NVRAM variables. The mitigation described is to a...
