CVE-2026-72197

The CVE-2026-72197 issue affects the Linux kernel, specifically the fs/ntfs3 path for DeleteIndexEntryAllocation. The root cause is that e->size can cause an overlong memmove when e + e->size points past hdr + hdr->used, leading to a dangerous memmove length. A corresponding guard alread...

CVE-2026-72192

The CVE-2026-72192 issue affects the Linux kernel ntfs3 code. Specifically, indx_insert_into_root before hdr_insert_head can overrun a kmalloc(index_block_size) when shrinking root->index_block_size (e.g., to 512) after the root is populated. A crafted NTFS image triggers a memcpy of attacker-...

USN-8575-2 linux-aws, linux-aws-5.15, linux-aws-fips, linux-fips, linux-ibm, linux-nvidia vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

UBUNTU-CVE-2026-56135

In NTFS-3G through 2026.2.25, a heap-based buffer overflow exists in the function buildinheritedid in libntfs-3g/security.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by creating a file in a crafted...
