{"id":"CVE-2026-68135","summary":"net: hip04: fix RX buffer leak on build_skb failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hip04: fix RX buffer leak on build_skb failure\n\nWhen build_skb() fails in hip04_rx_poll(), the driver jumps to the\nrefill path without releasing the current RX buffer and its DMA mapping.\nInstalling a replacement buffer then overwrites the slot references and\nleaks both resources.\n\nKeep the current slot intact and return budget so NAPI retries the same\nbuffer.  Also free a newly allocated RX fragment when dma_map_single()\nfails.\n\nThis issue was found by an in-house static analysis tool.","modified":"2026-08-12T04:18:45.872876116Z","published":"2026-08-10T11:58:58.463Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68135.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/14fa65d10f5696b063a7d8d26e8291ea84a2c6ed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/67a7614bde310da006ab259f4f163d3fb0f9e253"},{"type":"WEB","url":"https://git.kernel.org/stable/c/80d977f280b4eccd4ac5369871d0ecb2b9c9a49d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a0f247d63489a107bbc3b712a77b302af2a2a173"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e054dcd990d8180cde529ea28ce0838e76a5ad5e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68135.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68135"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"701a0fd5231866db08cebcd502894699f49cb960"},{"fixed":"e054dcd990d8180cde529ea28ce0838e76a5ad5e"},{"fixed":"67a7614bde310da006ab259f4f163d3fb0f9e253"},{"fixed":"80d977f280b4eccd4ac5369871d0ecb2b9c9a49d"},{"fixed":"a0f247d63489a107bbc3b712a77b302af2a2a173"},{"fixed":"14fa65d10f5696b063a7d8d26e8291ea84a2c6ed"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68135.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.5.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68135.json"}}],"schema_version":"1.9.0"}
