kernel: cxl/region: Avoid null pointer dereference in region lookup

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Avoid null pointer dereference in region lookup cxldpatoregion looks up a region based on a memdev and DPA. It wrongly assumes an endpoint found mapping the DPA is also of a fully assembled region. When not true it...

kernel: cxl/mem: Fix no cxl_nvd during pmem region auto-assembling

In the Linux kernel, the following vulnerability has been resolved: cxl/mem: Fix no cxlnvd during pmem region auto-assembling When CXL subsystem is auto-assembling a pmem region during cxl endpoint port probing, always hit below calltrace. BUG: kernel NULL pointer dereference, address:...

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: iommu: Don't reserve 0-length IOVA region

A flaw was found in the Linux kernel. When the bootloader/firmware does not set up the framebuffers, the address and size are 0 in the "iommu-addresses" property. If the IOVA region is reserved with a 0 length, it corrupts the IOVA rbtree with an entry that has pfnhi pfnlo. If the intent is to us...

CVE-2024-50248

CVE-2024-50248 affects the Linux kernel’s ntfs3 component. The advisory states that bounds checking was added to mi_enum_attr() to ensure attributes do not strays beyond valid memory regions, mitigating a memory-safety issue. The entry is resolved in the Linux kernel by updating to a patched vers...

CVE-2024-50226

CVE-2024-50226 : Linux kernel vulnerability in the CXL port code. A use-after-free during teardown of a region with multiple endpoint decoders (example: decoders 7.0 and 14.0 sharing a switch-decoder 3.0) could allow out-of-order shutdown and leave stale references. The patch ensures: (1) proper ...

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...
