Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.220.72

medium Tenable Cloud Security Plugin ID 472473

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: check return value of
 indx_find to avoid infinite loop We found an infinite loop bug in the ntfs3 file system that can lead to a
 Denial-of-Service (DoS) condition. A malformed dentry in the ntfs3 filesystem can cause the kernel to hang
 during the lookup operations. By setting the HAS_SUB_NODE flag in an INDEX_ENTRY within a directory's
 INDEX_ALLOCATION block and manipulating the VCN pointer, an attacker can cause the indx_find() function to
 repeatedly read the same block, allocating 4 KB of memory each time. The kernel lacks VCN loop detection
 and depth limits, causing memory exhaustion and an OOM crash. This patch adds a return value check for
 fnd_push() to prevent a memory exhaustion vulnerability caused by infinite loops. When the index exceeds
 the size of the fnd->nodes array, fnd_push() returns -EINVAL. The indx_find() function checks this return
 value and stops processing, preventing further memory allocation. (CVE-2025-71266)

Solution

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