medium Tenable Self-Hosted Container Security Plugin ID 451580

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: ipv6: mcast: fix data-race in
ipv6_mc_down / mld_ifc_work idev->mc_ifc_count can be written over without proper locking. Originally
found by syzbot [1], fix this issue by encapsulating calls to mld_ifc_stop_work() (and mld_gq_stop_work()
for good measure) with mutex_lock() and mutex_unlock() accordingly as these functions should only be
called with mc_lock per their declarations. [1] BUG: KCSAN: data-race in ipv6_mc_down / mld_ifc_work write
