kernel: KVM: arm64: Disassociate vcpus from redistributor region on teardown

A vulnerability was found in the Linux kernel's KVM for ARM64 within the vgic-init.c, vgic-mmio-v3.c, and vgic.h files. The virtual vCPUs may retain dangling pointers in a redistributor region after they have been torn down, leading to potential memory corruption...

kernel: mm/sparsemem: fix race in accessing memory_section->usage

A race condition was found on a PFN in the Linux Kernel, which can fall into the device memory region with the system memory configuration. Normal zone start and end PFNs contain the device memory PFNs as well, and the compaction triggered will try on the device memory PFNs and end up in NOP. Thi...

kernel: perf/x86/lbr: Filter vsyscall addresses

In the Linux kernel, the following vulnerability has been resolved: perf/x86/lbr: Filter vsyscall addresses We found that a panic can occur when a vsyscall is made while LBR sampling is active. If the vsyscall is interrupted NMI for perf sampling, this call sequence can occur most recent at top:...
