CVE-2026-80855

CVE-2026-80855 affects the Linux kernel FUSE filesystem. In fuse_open(), when a DAX truncate (O_TRUNC) triggers filemap_invalidate_lock(), a subsequent failure in fuse_dax_break_layouts() (e.g., returning -ERESTARTSYS after a signal interrupts the wait for busy DAX pages to drain) causes the code...

CVE-2026-80806

CVE-2026-80806 is a flaw in the Linux kernel's ext4 filesystem where newly created encrypted files could incorrectly have the DAX (Direct Access) flag enabled when the filesystem is mounted with -o dax=always. The root cause is a timing issue in __ext4_new_inode(): the call to ext4_set_inode_flag...

In the Linux kernel, the following vulnerability has been resolved: dax: Fixed the issue where daxmappingrelease was called after the free operation. A test using CONFIGDEBUGKOBJECTRELEASE to remove a device-related dax region e.g., using modprobe -r daxhmem results in the following output:...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/pagetablecheck: A crash occurred when checking ZONEDEVICE. Not all pages apply to the pgtable check. An example is ZONEDEVICE pages: they directly map PFNs, and they never allocate pageext, even if there’s a struct page around...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ext2/dax: Fixed ext2setsize when len is page-aligned. The PAGEALIGNx macro returns the next highest value that is a multiple of the page size. However, if x is already page-aligned, it simply returns x. Therefore, if x is passed ...

CVE-2026-74379

A flaw was found in the Linux kernel's dax/kmem module. This vulnerability occurs when the system attempts to remove a memory resource that was not fully initialized, leading to an attempt to access a null pointer. A local attacker could potentially trigger this condition, causing the system to...

CVE-2026-72172

A flaw was found in the Linux kernel. When Direct Access DAX memory is hotplugged, certain internal memory structures struct pages may not be fully initialized. This uninitialized state can lead to unexpected system behavior or crashes, potentially resulting in a denial of service...
