CVE-2024-36936

The CVE-2024-36936 issue affects the Linux kernel's memory-accept path under efi/unaccepted. The root cause was a soft lockup scenario caused by a spinlock held during memory acceptance, which could intermittently trigger a watchdog/softlockup on the CPU during large TD guest memory loads. The fi...

CVE-2021-47228

In the Linux kernel, the following vulnerability has been resolved: x86/ioremap: Map EFI-reserved memory as encrypted for SEV Some drivers require memory that is marked as EFI boot services data. In order for this memory to not be re-used by the kernel after ExitBootServices, efimemreserve is use...

grub2: out-of-bounds read at fs/ntfs.c

An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to...
