This function\nuses the skb_cow_head() to ensure that there is sufficient headroom in\nthe sk_buff for accommodating the link-layer header.\nIn the event that the skb_cow_header() function fails, the\nseg6_input_core() catches the error but it does not release the sk_buff,\nwhich will result in a memory leak.\n\nThis issue was introduced in commit af3b5158b89d (\"ipv6: sr: fix BUG due\nto headroom too small after SRH push\") and persists even after commit\n7a3f5b0de364 (\"netfilter: add netfilter hooks to SRv6 data plane\"),\nwhere the entire seg6_input() code was refactored to deal with netfilter\nhooks.\n\nThe proposed patch addresses the identified memory leak by requiring the\nseg6_input_core() function to release the sk_buff in the event that\nskb_cow_head() fails."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/ipv6/seg6_iptunnel.c"],"versions":[{"version":"af3b5158b89d3bab9be881113417558c71b71ca4","lessThan":"e8688218e38111ace457509d8f0cad75f79c1a7a","status":"affected","versionType":"git"},{"version":"af3b5158b89d3bab9be881113417558c71b71ca4","lessThan":"8f1fc3b86eaea70be6abcae2e9aa7e7b99453864","status":"affected","versionType":"git"},{"version":"af3b5158b89d3bab9be881113417558c71b71ca4","lessThan":"f4df8c7670a73752201cbde215254598efdf6ce8","status":"affected","versionType":"git"},{"version":"af3b5158b89d3bab9be881113417558c71b71ca4","lessThan":"f5fec1588642e415a3d72e02140160661b303940","status":"affected","versionType":"git"},{"version":"af3b5158b89d3bab9be881113417558c71b71ca4","lessThan":"5447f9708d9e4c17a647b16a9cb29e9e02820bd9","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/ipv6/seg6_iptunnel.c"],"versions":[{"version":"4.12","status":"affected"},{"version":"0","lessThan":"4.12","status":"unaffected","versionType":"semver"},{"version":"5.15.161","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.93","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.33","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.4","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","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":"4.12","versionEndExcluding":"5.15.161"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.1.93"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.6.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.9.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.12","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/e8688218e38111ace457509d8f0cad75f79c1a7a"},{"url":"https://git.kernel.org/stable/c/8f1fc3b86eaea70be6abcae2e9aa7e7b99453864"},{"url":"https://git.kernel.org/stable/c/f4df8c7670a73752201cbde215254598efdf6ce8"},{"url":"https://git.kernel.org/stable/c/f5fec1588642e415a3d72e02140160661b303940"},{"url":"https://git.kernel.org/stable/c/5447f9708d9e4c17a647b16a9cb29e9e02820bd9"}],"title":"ipv6:
