Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 458573

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: team: Move team device type change at
 the end of team_port_add Attempting to add a port device that is already up will expectedly fail, but not
 before modifying the team device header_ops. In the case of the syzbot reproducer the gre0 device is
 already in state UP when it attempts to add it as a port device of team0, this fails but before that
 header_ops->create of team0 is changed from eth_header to ipgre_header in the call to
 team_dev_type_check_change. Later when we end up in ipgre_header() struct ip_tunnel* points to nonsense as
 the private data of the device still holds a struct team. Example sequence of iproute2 commands to
 reproduce the hang/BUG(): ip link add dev team0 type team ip link add dev gre0 type gre ip link set dev
 gre0 up ip link set dev gre0 master team0 ip link set dev team0 up ping -I team0 1.1.1.1 Move
 team_dev_type_check_change down where all other checks have passed as it changes the dev type with no way
 to restore it in case one of the checks that follow it fail. Also make sure to preserve the origial mtu
 assignment: - If port_dev is not the same type as dev, dev takes mtu from port_dev - If port_dev is the
 same type as dev, port_dev takes mtu from dev This is done by adding a conditional before the call to
 dev_set_mtu to prevent it from assigning port_dev->mtu = dev->mtu and instead letting
 team_dev_type_check_change assign dev->mtu = port_dev->mtu. The conditional is needed because the patch
 moves the call to team_dev_type_check_change past dev_set_mtu. Testing: - team device driver in-tree
 selftests - Add/remove various devices as slaves of team device - syzbot (CVE-2025-68340)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
