CVE-2022-1158 – kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region
https://notcve.org/view.php?id=CVE-2022-1158
12 May 2022 — A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition. Se ha encontrado un fallo en KVM. Cuando era actualizada la entrada de la tabla de páginas de un huésped, vm_pgoff era usado incorrectamente com... • https://bugzilla.redhat.com/show_bug.cgi?id=2069793 • CWE-416: Use After Free •
CVE-2021-4037 – kernel: security regression for CVE-2018-13405
https://notcve.org/view.php?id=CVE-2021-4037
11 May 2022 — A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not.
