medium Tenable Self-Hosted Container Security Plugin ID 469645

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: ntfs3: add buffer boundary checks to
run_unpack() run_unpack() checks `run_buf < run_last` at the top of the while loop but then reads
size_size and offset_size bytes via run_unpack_s64() without verifying they fit within the remaining
buffer. A crafted NTFS image with truncated run data in an MFT attribute triggers an OOB heap read of up
to 15 bytes when the filesystem is mounted. Add boundary checks before each run_unpack_s64() call to
ensure the declared field size does not exceed the remaining buffer. Found by fuzzing with a source-
patched harness (LibAFL + QEMU). (CVE-2026-46072)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.224.7 or later.
