nf_tables: make nft_object rhltable per table","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: make nft_object rhltable per table\n\nThe nft_object rhltable is global, this allows for accessing objects\nthat are being dismangled from lookup path by other existing netns.\nGiven the nft_obj_destroy() releases the object inmediately, this might\nlead to use-after-free of these objects that are being released.\nMake the existing rhltable per table to address this issue to deal with\nwith the nft_rcv_nl_event() path too.\n\nUpdate nft_obj_lookup() to take the table as non-const, otherwise,\ncompiler complains when passing the objname_ht to rhltable_lookup().","state":0,"publishedAt":"2026-08-15T12:28:07.015+00:00","modifiedAt":"2026-10-21T12:45:59.495+00:00","affected":[{"ecosystem":"Vendor
