The Linux Kernel, the operating system core itself. Security Fixes: A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget which are aligned to PUD alignment with the fault of some of the memory pages. A local...

kernel: Overlayfs in the Linux kernel and shiftfs not restoring original value on error leading to a refcount underflow

A flaw was found in the Linux kernel. In Overlayfs, vma-vmfile was replaced in the mmap handlers and, on errors, the original value is not restored. A local attacker with special user privilege or root can cause a kernel internal information leak. The highest threat from this vulnerability is to...

CVE-2021-28695

CVE-2021-28695 affects the Xen hypervisor (IOMMU page mapping) on AMD systems. The issue arises when firmware specifies discontinuous memory ranges that are identity-mapped during translation, allowing a guest to retain access to memory ranges it should not access after device de-assignment. Docu...
