CVE-2024-27031

CVE-2024-27031 (Linux kernel) : The NFS read path (nfs_netfs_issue_read) locked with xa_lock while submitting pages for writeback, but did not disable interrupts during iteration, creating a deadlock risk if an interrupt runs and touches the xa_lock. The fix replaces manual iteration with xa_for_...

CVE-2024-26991

The Linux kernel is vulnerable to a vmalloc out-of-bounds read within the KVM x86/mmu component. The issue occurs because the KVM_SET_MEMORY_ATTRIBUTES ioctl operation utilizes an optimization in the hugepage_has_attrs() helper function. While level-1 huge pages are checked first to determine if ...
