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: macvlan: fix macvlan_get_size() not
 reserving space for IFLA_MACVLAN_BC_CUTOFF macvlan_get_size() does not account for IFLA_MACVLAN_BC_CUTOFF,
 but macvlan_fill_info() conditionally includes it when port->bc_cutoff != 1. This causes nla_put_s32() to
 fail with -EMSGSIZE when the netlink skb runs out of space, triggering a WARN_ON in rtnetlink and
 preventing the interface from being dumped. The bug can be reproduced with: ip link add macvlan0 link eth0
 type macvlan mode bridge ip link set macvlan0 type macvlan bc_cutoff 0 ip -d link show macvlan0 # fails
 with -EMSGSIZE The bc_cutoff feature was added in commit 954d1fa1ac93 ("macvlan: Add netlink attribute for
 broadcast cutoff"), which added the nla_put_s32() call in macvlan_fill_info() but missed adding the
 corresponding nla_total_size(4) in macvlan_get_size(). A follow-up commit 55cef78c244d ("macvlan: add
 forgotten nla_policy for IFLA_MACVLAN_BC_CUTOFF") fixed the missing nla_policy entry but still did not fix
 the size calculation. (CVE-2026-53013)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.613.77 or later.
