RawHive

RawHive RawHive is a Cobalt Strike BOF for pulling selected Windows registry hives directly from a raw NTFS volume. It skips the normal file APIs, walks NTFS metadata to find the target file records, and copies the bytes straight from disk. It currently looks for: C:\Windows\System32\config\SAM...

page_table_walk

Capture the Flag in Physical Memory You've read about paging. The diagrams make sense. Four levels, 9 bits each, page frame, offset. Sure. But then you hit a challenge that requires actually walking page tables, and you realize you don't know it. You know about it. Big difference. What worked for...

SUSE CVE-2026-80869

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the attribute-list entry in ntfsreadinodemount The $MFT attribute-list walk in ntfsreadinodemount validates each entry only with "u8 alentry + 6 alend" and "u8 alentry + le16tocpualentry-length alend", but then reads...

CVE-2026-80869

CVE-2026-80869 affects the Linux kernel NTFS filesystem driver. In ntfs_read_inode_mount() , the $MFT attribute-list walk validated only that 6 bytes of each entry were in range, then read lowest_vcn (offset 8, 8 bytes) and mft_reference (offset 16) — fields beyond the proven boundary. Since al_e...

CVE-2026-80800

CVE-2026-80800 affects the Linux kernel NFC LLCP subsystem. The function nfc_llcp_connect_sn() walks a TLV list without validating that the two-byte header or declared length stay within the skb buffer, and computes tlv_array_len as skb->len - LLCP_HEADER_SIZE in size_t, causing an underflow f...

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...
