{"id":"CVE-2026-53355","summary":"net: rds: clear i_sends on setup unwind","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: rds: clear i_sends on setup unwind\n\nThe RDS IB connection teardown path is written so it can run during\npartial startup and on repeated shutdown attempts. It uses NULL\npointers to distinguish resources that are still owned from resources\nthat have already been released.\n\nWhen rds_ib_setup_qp() fails after allocating i_sends but before\nallocating i_recvs, the sends_out path frees i_sends without clearing\nthe pointer. A later shutdown pass can still treat that stale pointer\nas a live send ring allocation.\n\nClear i_sends after vfree() in the error unwind path so the existing\nshutdown logic continues to use the correct ownership state.","modified":"2026-10-28T02:31:03.796840916Z","published":"2026-07-01T13:32:30.831Z","related":["SUSE-SU-2026:23066-1","SUSE-SU-2026:23068-1","SUSE-SU-2026:23193-1","SUSE-SU-2026:23194-1","SUSE-SU-2026:23221-1","SUSE-SU-2026:23231-1","SUSE-SU-2026:23237-1","SUSE-SU-2026:23241-1","SUSE-SU-2026:23244-1","SUSE-SU-2026:3130-1","SUSE-SU-2026:3166-1","SUSE-SU-2026:3594-1","openSUSE-SU-2026:21555-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53355.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1d4ec754ee3871f7e3670c67bb0298c9c5760926"},{"type":"WEB","url":"https://git.kernel.org/stable/c/20cf0fb715c41111469577e85e35d15f099473e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/27040bbca289a704eafcacca167d310c6ce2b1bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/29d940026dce39e3018dab6f67c9427249321270"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c5e5e4a5970c41f16e3ad801a78719ed5d5c71b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66cccec111421a10efdc2c74499d15b93e7acae5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e7cf30aa5f1fc6c2a86df65df8b731df20e44d79"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f16ad421a4e3e7db2d14bdf3b16f583bc4f3b30a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53355.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53355"},{"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":"3b12f73a5c2977153f28a224392fd4729b50d1dc"},{"fixed":"66cccec111421a10efdc2c74499d15b93e7acae5"},{"fixed":"2c5e5e4a5970c41f16e3ad801a78719ed5d5c71b"},{"fixed":"29d940026dce39e3018dab6f67c9427249321270"},{"fixed":"e7cf30aa5f1fc6c2a86df65df8b731df20e44d79"},{"fixed":"f16ad421a4e3e7db2d14bdf3b16f583bc4f3b30a"},{"fixed":"1d4ec754ee3871f7e3670c67bb0298c9c5760926"},{"fixed":"27040bbca289a704eafcacca167d310c6ce2b1bc"},{"fixed":"20cf0fb715c41111469577e85e35d15f099473e0"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3.18.74"},{"fixed":"3.19"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.1.46"},{"fixed":"4.2"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.4.91"},{"fixed":"4.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.9.54"},{"fixed":"4.10"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"75a12b2fa80c2e4cc40a9f9305f95899850b7426"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c9459693fae9a1bf3f51f3db98617f694112e897"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"13099ee9c7d54b0a25f6c8397675aed99e9cfa45"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5c6712ab4efb6cf60e16719ab6bcaface9cc268c"}]}],"versions":["v3.18.140","v3.18.139","v3.18.138","v3.18.137","v3.18.136","v3.18.135","v3.18.134","v3.18.133","v3.18.132","v3.18.131","v3.18.130","v3.18.129","v3.18.128","v3.18.127","v3.18.126","v3.18.125","v3.18.124","v3.18.123","v3.18.122","v3.18.121","v3.18.120","v3.18.119","v3.18.118","v3.18.117","v3.18.116","v3.18.115","v3.18.114","v3.18.113","v3.18.112","v3.18.111","v3.18.110","v3.18.109","v3.18.108","v3.18.107","v3.18.106","v3.18.105","v3.18.104","v3.18.103","v3.18.102","v3.18.101","v3.18.100","v3.18.99","v3.18.98","v3.18.97","v3.18.96","v3.18.95","v3.18.94","v3.18.93","v3.18.92","v3.18.91","v3.18.90","v3.18.89","v3.18.88","v3.18.87","v3.18.86","v3.18.85","v3.18.84","v3.18.83","v3.18.82","v3.18.81","v3.18.80","v3.18.79","v3.18.78","v3.18.77","v3.18.76","v3.18.75","v3.18.74","v4.1.52","v4.1.51","v4.1.50","v4.1.49","v4.1.48","v4.1.47","v4.1.46","v4.4.302","v4.4.301","v4.4.300","v4.4.299","v4.4.298","v4.4.297","v4.4.296","v4.4.295","v4.4.294","v4.4.293","v4.4.292","v4.4.291","v4.4.290","v4.4.289","v4.4.288","v4.4.287","v4.4.286","v4.4.285","v4.4.284","v4.4.283","v4.4.282","v4.4.281","v4.4.280","v4.4.279","v4.4.278","v4.4.277","v4.4.276","v4.4.275","v4.4.274","v4.4.273","v4.4.272","v4.4.271","v4.4.270","v4.4.269","v4.4.268","v4.4.267","v4.4.266","v4.4.265","v4.4.264","v4.4.263","v4.4.262","v4.4.261","v4.4.260","v4.4.259","v4.4.258","v4.4.257","v4.4.256","v4.4.255","v4.4.254","v4.4.253","v4.4.252","v4.4.251","v4.4.250","v4.4.249","v4.4.248","v4.4.247","v4.4.246","v4.4.245","v4.4.244","v4.4.243","v4.4.242","v4.4.241","v4.4.240","v4.4.239","v4.4.238","v
