We must call ->destroy function of the object.\n\nnft_obj_destroy does this, but it also decrements the module refcount,\nbut the update path doesn't increment it.\n\nTo avoid special-casing the update object release, do module_get for\nthe update case too and release it via nft_obj_destroy()."}],"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":"d62d0ba97b5803183e70cfded7f7b9da76893bf5","lessThan":"53026346a94c43f35c32b18804041bc483271d87","status":"affected","versionType":"git"},{"version":"d62d0ba97b5803183e70cfded7f7b9da76893bf5","lessThan":"7e9880e81d3fd6a43c202f205717485290432826","status":"affected","versionType":"git"},{"version":"d62d0ba97b5803183e70cfded7f7b9da76893bf5","lessThan":"e96e204ee6fa46702f6c94c3c69a09e69e0eac52","status":"affected","versionType":"git"},{"version":"d62d0ba97b5803183e70cfded7f7b9da76893bf5","lessThan":"34bb90e407e3288f610558beaae54ecaa32b11c4","status":"affected","versionType":"git"},{"version":"d62d0ba97b5803183e70cfded7f7b9da76893bf5","lessThan":"dad3bdeef45f81a6e90204bcc85360bb76eccec7","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":"5.4","status":"affected"},{"version":"0","lessThan":"5.4","status":"unaffected","versionType":"semver"},{"version":"5.4.182","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.103","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.26","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.16.12","lessThanOrEqual":"5.16.*","status":"unaffected","versionType":"semver"},{"version":"5.17","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","versionEndExcluding":"5.4.182"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4","versionEndExcluding":"5.10.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4","versionEndExcluding":"5.15.26"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4","versionEndExcluding":"5.16.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4","versionEndExcluding":"5.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/53026346a94c43f35c32b18804041bc483271d87"},{"url":"https://git.kernel.org/stable/c/7e9880e81d3fd6a43c202f205717485290432826"},{"url":"https://git.kernel.org/stable/c/e96e204ee6fa46702f6c94c3c69a09e69e0eac52"},{"url":"https://git.kernel.org/stable/c/34bb90e407e3288f610558beaae54ecaa32b11c4"},{"url":"https://git.kernel.org/stable/c/dad3bdeef45f81a6e90204bcc85360bb76eccec7"}],"title":"netfilter: nf_tables: fix memory leak during stateful obj update","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2022-48933","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T15:32:43.489248Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-12T17:32:59.806Z"}}]}}
