CVE-2026-52792

Algernon is a small self-contained pure-Go web server. Prior to 1.17.9, Algernon on Windows selects a file handler in engine/handlers.go by calling filepath.Ext without first rejecting NTFS-equivalent names such as x.lua::$DATA, x.lua., and x.lua . An unauthenticated client can append one of thes...

CVE-2026-52792

Algernon (a pure-Go web server) prior to 1.17.9 is vulnerable to server-side script source disclosure on Windows via NTFS filename aliasing. The root cause is in engine/handlers.go: filepath.Ext() does not recognize NTFS-equivalent suffixes (::$DATA, trailing dot, trailing space) as the script ex...

CVE-2026-72210

A flaw was found in the Linux kernel's NTFS filesystem driver. An error in how the driver checks the boundaries of data it processes, specifically an 'off-by-one' error, allows it to read one byte beyond its intended memory region. This 'out-of-bounds read' could potentially lead to the disclosur...

CVE-2026-72209

A flaw was found in the Linux kernel's NTFS filesystem driver. A local attacker could craft a malicious NTFS image that causes the kernel to read beyond the intended memory boundary when processing $FILENAME attributes. This out-of-bounds read could lead to information disclosure or potentially a...

CVE-2026-72208

A flaw was found in the Linux kernel's NTFS file system driver. A missing bounds check when processing Extended Attribute EA entries in the ntfsealookup and ntfslistxattr functions could allow a local attacker to craft a malicious NTFS file system. When this file system is mounted, it could lead ...

CVE-2026-72207

A flaw was found in the NTFS file system driver in the Linux kernel. When the ntfsresidentattrresize function attempts to free space by converting resident attributes to non-resident, it incorrectly selects zero-length $DATA attributes for this conversion. This can lead to fsck file system check...

CVE-2026-72206

A flaw was found in the Linux kernel's NTFS filesystem driver. Insufficient validation of index block headers within INDX blocks could allow a local attacker to craft a malicious NTFS filesystem image. When this image is processed by the kernel, it could lead to a kernel panic due to an...

CVE-2026-72205

A flaw was found in the Linux kernel's NTFS filesystem driver. When an attempt to mount an NTFS volume fails, the ntfsfillsuper function's error handling path does not properly free all volume-wide resources. This oversight leads to a silent resource leak, where memory and other resources...

CVE-2026-72204

A flaw was found in the Linux kernel's NTFS file system driver. This vulnerability arises from insufficient validation of the $INDEXROOT header, which is crucial for managing directory and file indexes. An attacker could potentially craft a specially malformed NTFS file system. Processing this...

CVE-2026-72202

A flaw was found in the Linux kernel's NTFS filesystem driver. When calculating free clusters or Master File Table MFT records, a temporary state object is allocated on the heap. If this allocation fails, processes waiting for these counts can become unresponsive, leading to a denial of service D...

CVE-2026-72201

A flaw was found in the Linux kernel's New Technology File System NTFS implementation. This vulnerability arises from insufficient validation of index entries when reading index roots or blocks from disk. An attacker could potentially craft a malicious NTFS filesystem, which, when processed by th...

CVE-2026-72187

A flaw was found in the Linux kernel's NTFS file system driver. An attacker with local access could trigger a self-deadlock condition during inode eviction. This occurs when an attribute-list update during cluster allocation causes a temporary inode to lose its last reference, leading to an...

CVE-2026-72186

A flaw was found in the Linux kernel's NTFS driver. A local user could exploit this by writing to specific system files, such as $Bitmap, which are exposed through the showsysfiles interface. This unauthorized write access can lead to file system corruption and potentially cause a system deadlock...

CVE-2026-72200

A flaw was found in the Linux kernel's NTFS mapping-pairs parser. A corrupted attribute can cause a signed integer overflow when processing Logical Cluster Number LCN deltas. This overflow leads to undefined behavior, which may result in the system incorrectly interpreting file system structures...

CVE-2026-72203

A flaw was found in the Linux kernel. This flaw involves a deadlock condition within the NTFS file system's writeback mechanism. Specifically, an ABBA deadlock can occur between the extentlock and mreclock during inode and MFT Master File Table folio writeback operations. This could lead to a...

CVE-2026-72211

A flaw was found in the Linux kernel's NTFS file system driver. When the driver attempts to reparent an index root, it can update metadata to reflect a larger size before the actual data structure is resized. If this resize operation fails, the file system can enter an inconsistent state. This...

CVE-2026-72185

A flaw was found in the Linux kernel's NTFS filesystem driver. A specially crafted NTFS image could cause the system to incorrectly process attribute data during mounting. This could lead to a kernel warning and corruption of internal data structures, potentially resulting in system instability o...
