the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout\n\nWhile the rhashtable set gc runs asynchronously, a race allows it to\ncollect elements from anonymous sets with timeouts while it is being\nreleased from the commit path.\n\nMingi Cho originally reported this issue in a different path in 6.1.x\nwith a pipapo set with low timeouts which is not possible upstream since\n7395dfacfff6 (\"netfilter: nf_tables: use timestamp to check for set\nelement timeout\").\n\nFix this by setting on the dead flag for anonymous sets to skip async gc\nin this case.\n\nAccording to 08e4c8c5919f (\"netfilter: nf_tables: mark newset as dead on\ntransaction abort\"), Florian plans to accelerate abort path by releasing\nobjects via workqueue, therefore, this sets on the dead flag for abort\npath too."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/netfilter/nf_tables_api.c"],"versions":[{"version":"8da1b048f9a501d3d7d38c188ba09d7d0d5b8c27","lessThan":"d75a589bb92af1abf3b779cfcd1977ca11b27033","status":"affected","versionType":"git"},{"version":"bbdb3b65aa91aa0a32b212f27780b28987f2d94f","lessThan":"edcf1a3f182ecf8b6b805f0ce90570ea98c5f6bf","status":"affected","versionType":"git"},{"version":"448be0774882f95a74fa5eb7519761152add601b","lessThan":"e2d45f467096e931044f0ab7634499879d851a5c","status":"affected","versionType":"git"},{"version":"d19e8bf3ea4114dd21fc35da21f398203d7f7df1","lessThan":"291cca35818bd52a407bc37ab45a15816039e363","status":"affected","versionType":"git"},{"version":"ea3eb9f2192e4fc33b795673e56c97a21987f868","lessThan":"406b0241d0eb598a0b330ab20ae325537d8d8163","status":"affected","versionType":"git"},{"version":"5f68718b34a531a556f2f50300ead2862278da26","lessThan":"b2d6f9a5b1cf968f1eaa71085ceeb09c2cb276b1","status":"affected","versionType":"git"},{"version":"5f68718b34a531a556f2f50300ead2862278da26","lessThan":"5224afbc30c3ca9ba23e752f0f138729b2c48dd8","status":"affected","versionType":"git"},{"version":"5f68718b34a531a556f2f50300ead2862278da26","lessThan":"552705a3650bbf46a22b1adedc1b04181490fc36","status":"affected","versionType":"git"},{"version":"0624f190b5742a1527cd938295caa8dc5281d4cd","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/netfilter/nf_tables_api.c"],"versions":[{"version":"6.5","status":"affected"},{"version":"0","lessThan":"6.5","status":"unaffected","versionType":"semver"},{"version":"5.4.274","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.215","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.154","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.84","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.24","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.12","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4.262","versionEndExcluding":"5.4.274"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10.198","versionEndExcluding":"5.10.215"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15.134","versionEndExcluding":"5.15.154"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.56","versionEndExcluding":"6.1.84"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.6.24"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.7.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d75a589bb92af1abf3b779cfcd1977ca11b27033"},{"url":"https://git.kernel.org/stable/c/edcf1a3f182ecf8b6b805f0ce90570ea98c5f6bf"},{"url":"https://git.kernel.org/stable/c/e2d45f467096e931044f0ab7634499879d851a5c"},{"url":"https://git.kernel.org/stable/c/291cca35818bd52a407bc37ab45a15816039e363"},{"url":"https://git.kernel.org/stable/c/406b0241d0eb598a0b330ab20ae325537d8d8163"},{"url":"https://git.kernel.org/stable/c/b2d6f9a5b1cf968f1eaa71085ceeb09c2cb276b1"},{"url":"https://git.kernel.org/stable/c/5224afbc30c3ca9ba23e752f0f138729b2c48dd8"},{"url":"https://git.kernel.org/stable/c/552705a3650bbf46a22b1adedc1b04181490fc36"}],"title":"netfilter:
