The vulnerability of the svm_vcpu_pre_run() function in the arch/x86/kvm/svm/svm.c module of the virtualization subsystem on the x86 kernel of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the svmvcpuprerun function in the arch/x86/kvm/svm/svm.c module of the virtualization subsystem on the Linux kernel-based x86 platform is related to insufficient checking of exception states. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2025-38071 x86/mm: Check return value from memblock_phys_alloc_range()

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Check return value from memblockphysallocrange At least with CONFIGPHYSICALSTART=0x100000, if there is 4 MiB of contiguous free memory available at this point, the kernel will crash and burn because memblockphysallocrange...

kernel: Mishandling of indirect calls weakens Spectre mitigation for paravirtual guests

It was found that paravirtpatchcall/jump functions in the arch/x86/kernel/paravirt.c in the Linux kernel mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtualized guests...
