the Linux kernel, the following vulnerability has been resolved:\n\nnet: openvswitch: fix possible kfree_skb of ERR_PTR\n\nAfter the patch in the \"Fixes\" tag, the allocation of the \"reply\" skb\ncan happen either before or after locking the ovs_mutex.\n\nHowever, error cleanups still follow the classical reversed order,\nassuming \"reply\" is allocated before locking: it is freed after unlocking.\n\nIf \"reply\" allocation happens after locking the mutex and it fails,\n\"reply\" is left with an ERR_PTR, and execution jumps to the correspondent\ncleanup stage which will try to free an invalid pointer.\n\nFix this by setting the pointer to NULL after having saved its error\nvalue."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/openvswitch/datapath.c"],"versions":[{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"e248fb2e680deb2bd37bac551b72638fe4938a76","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"0bb5b2dc1b90aa7dd1473fc8c4d813a29255ff8d","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"971b1b37774f13acc5add0a2843f8598446b8598","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"25fdf53698535fe8790237f5a8a9626791429785","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"e3d509a1b71396e1452060dbf84a805fd1c3c549","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"ecc55aad3390129a87106841f4b68bf3d70c9264","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"895d1dd9057cde1687fa0f4286d47ceed0b82997","status":"affected","versionType":"git"},{"version":"893f139b9a6c00c097b9082a90f3041cfb3a0d20","lessThan":"ee30dd2909d8b98619f4341c70ec8dc8e155ab02","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/openvswitch/datapath.c"],"versions":[{"version":"3.16","status":"affected"},{"version":"0","lessThan":"3.16","status":"unaffected","versionType":"semver"},{"version":"5.10.259","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.210","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.176","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.143","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.94","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.36","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.13","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"3.16","versionEndExcluding":"5.10.259"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.15.210"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.1.176"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.6.143"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.12.94"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.18.36"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"7.0.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/e248fb2e680deb2bd37bac551b72638fe4938a76"},{"url":"https://git.kernel.org/stable/c/0bb5b2dc1b90aa7dd1473fc8c4d813a29255ff8d"},{"url":"https://git.kernel.org/stable/c/971b1b37774f13acc5add0a2843f8598446b8598"},{"url":"https://git.kernel.org/stable/c/25fdf53698535fe8790237f5a8a9626791429785"},{"url":"https://git.kernel.org/stable/c/e3d509a1b71396e1452060dbf84a805fd1c3c549"},{"url":"https://git.kernel.org/stable/c/ecc55aad3390129a87106841f4b68bf3d70c9264"},{"url":"https://git.kernel.org/stable/c/895d1dd9057cde1687fa0f4286d47ceed0b82997"},{"url":"https://git.kernel.org/stable/c/ee30dd2909d8b98619f4341c70ec8dc8e155ab02"}],"title":"net:
