An out-of-bound write vulnerability was identified within the netfilter subsystem in linux kernel before v4.9.313,v4.14.278,v4.19.242,v5.4.193,v5.10.115,v5.15.39,v5.17.7, and v5.18-rc6, which can be exploited to achieve privilege escalation to root. The netfilter subsystem did not properly validate sets with multiple ranged fields. A local attacker could use this to cause a denial of service or execute arbitrary code.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
