high Tenable Cloud Security Plugin ID 468724

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: smb: client: fix overflow in
 passthrough ioctl bounds check smb2_ioctl_query_info() validates the PASSTHRU_FSCTL response payload
 before copying it to userspace. The payload offset and length both come from 32-bit fields. The bounds
 check currently adds OutputOffset and qi.input_buffer_length directly, so the addition can wrap in 32-bit
 arithmetic before the result is compared against the response buffer length. A malicious server can use a
 large OutputOffset and a small OutputCount to make the wrapped sum pass the bounds check. The later
 copy_to_user() then reads from io_rsp + OutputOffset, outside the response buffer. Use size_add() for the
 offset plus length check so overflow is treated as out of bounds. (CVE-2026-72310)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
