Security Fixes: kernel: ksm: use range-walk function to jump over holes in scangetnextrmapitem CVE-2025-68211 kernel: isofs: validate Rock Ridge CE continuation extent against volume size CVE-2026-46303 kernel:...

kernel: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item

A resource exhaustion vulnerability was found in the Kernel Same-page Merging KSM subsystem of the Linux kernel. When scanning processes with large sparse virtual memory mappings e.g., 32 TiB with one mapped page, ksmd inefficiently walks every address rather than skipping unmapped holes. This...

The vulnerabilities of the functions xfs_reflink_fill_cow_hole() and xfs_reflink_fill_delalloc() in the fs/xfs/xfs_reflink.c module of the Linux operating system’s file system XFS allow attackers to influence the confidentiality, integrity, and accessibility of protected information.

The vulnerabilities of the functions xfsreflinkfillcowhole and xfsreflinkfilldelalloc in the fs/xfs/xfsreflink.c module of the Linux operating system’s file system are related to synchronization errors when using shared resources. Exploiting these vulnerabilities can allow attackers to compromise...
