medium Tenable Cloud Security Plugin ID 472467

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: fs: ntfs3: fix infinite loop triggered
 by zero-sized ATTR_LIST We found an infinite loop bug in the ntfs3 file system that can lead to a Denial-
 of-Service (DoS) condition. A malformed NTFS image can cause an infinite loop when an ATTR_LIST attribute
 indicates a zero data size while the driver allocates memory for it. When ntfs_load_attr_list() processes
 a resident ATTR_LIST with data_size set to zero, it still allocates memory because of al_aligned(0). This
 creates an inconsistent state where ni->attr_list.size is zero, but ni->attr_list.le is non-null. This
 causes ni_enum_attr_ex to incorrectly assume that no attribute list exists and enumerates only the primary
 MFT record. When it finds ATTR_LIST, the code reloads it and restarts the enumeration, repeating
 indefinitely. The mount operation never completes, hanging the kernel thread. This patch adds validation
 to ensure that data_size is non-zero before memory allocation. When a zero-sized ATTR_LIST is detected,
 the function returns -EINVAL, preventing a DoS vulnerability. (CVE-2025-71267)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.220.72 or later.
