VUL-0: CVE-2024-26835: kernel: netfilter: nf_tables: table marked as active but no registered hooks during memory pressure
Last modified: 2024-07-03 09:39:11 UTC
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: set dormant flag on hook register failure We need to set the dormant flag again if we fail to register the hooks. During memory pressure hook registration can fail and we end up with a table marked as active but no registered hooks. On table/base chain deletion, nf_tables will attempt to unregister the hook again which yields a warn splat from the nftables core.
