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 OOB read in
 smb2_ioctl_query_info QUERY_INFO path smb2_ioctl_query_info() has two response-copy branches:
 PASSTHRU_FSCTL and the default QUERY_INFO path. The QUERY_INFO branch clamps qi.input_buffer_length to the
 server-reported OutputBufferLength and then copies qi.input_buffer_length bytes from qi_rsp->Buffer to
 userspace, but it never verifies that the flexible-array payload actually fits within rsp_iov[1].iov_len.
 A malicious server can return OutputBufferLength larger than the actual QUERY_INFO response, causing
 copy_to_user() to walk past the response buffer and expose adjacent kernel heap to userspace. Guard the
 QUERY_INFO copy with a bounds check on the actual Buffer payload. Use struct_size(qi_rsp, Buffer,
 qi.input_buffer_length) rather than an open-coded addition so the guard cannot overflow on 32-bit builds.
 (CVE-2026-31708)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.5 or later.
