medium Tenable Self-Hosted Container Security Plugin ID 468908

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: net: bridge: fix soft lockup in
 br_multicast_query_expired() When set multicast_query_interval to a large value, the local variable 'time'
 in br_multicast_send_query() may overflow. If the time is smaller than jiffies, the timer will expire
 immediately, and then call mod_timer() again, which creates a loop and may trigger the following soft
 lockup issue. watchdog: BUG: soft lockup - CPU#1 stuck for 221s! [rb_consumer:66] CPU: 1 UID: 0 PID: 66
 Comm: rb_consumer Not tainted 6.16.0+ #259 PREEMPT(none) Call Trace: <IRQ> __netdev_alloc_skb+0x2e/0x3a0

 issue can be reproduced with: ip link add br0 type bridge echo 1 >
 /sys/class/net/br0/bridge/multicast_querier echo 0xffffffffffffffff >
 /sys/class/net/br0/bridge/multicast_query_interval ip link set dev br0 up The
 multicast_startup_query_interval can also cause this issue. Similar to the commit 99b40610956a ("net:
 bridge: mcast: add and enforce query interval minimum"), add check for the query interval maximum to fix
 this issue. (CVE-2025-39773)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.0.53 or later.
