{"id":"CVE-2026-43469","summary":"xprtrdma: Decrement re_receiving on the early exit paths","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxprtrdma: Decrement re_receiving on the early exit paths\n\nIn the event that rpcrdma_post_recvs() fails to create a work request\n(due to memory allocation failure, say) or otherwise exits early, we\nshould decrement ep-\u003ere_receiving before returning. Otherwise we will\nhang in rpcrdma_xprt_drain() as re_receiving will never reach zero and\nthe completion will never be triggered.\n\nOn a system with high memory pressure, this can appear as the following\nhung task:\n\n    INFO: task kworker/u385:17:8393 blocked for more than 122 seconds.\n          Tainted: G S          E       6.19.0 #3\n    \"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\n    task:kworker/u385:17 state:D stack:0     pid:8393  tgid:8393  ppid:2      task_flags:0x4248060 flags:0x00080000\n    Workqueue: xprtiod xprt_autoclose [sunrpc]\n    Call Trace:\n     \u003cTASK\u003e\n     __schedule+0x48b/0x18b0\n     ? ib_post_send_mad+0x247/0xae0 [ib_core]\n     schedule+0x27/0xf0\n     schedule_timeout+0x104/0x110\n     __wait_for_common+0x98/0x180\n     ? __pfx_schedule_timeout+0x10/0x10\n     wait_for_completion+0x24/0x40\n     rpcrdma_xprt_disconnect+0x444/0x460 [rpcrdma]\n     xprt_rdma_close+0x12/0x40 [rpcrdma]\n     xprt_autoclose+0x5f/0x120 [sunrpc]\n     process_one_work+0x191/0x3e0\n     worker_thread+0x2e3/0x420\n     ? __pfx_worker_thread+0x10/0x10\n     kthread+0x10d/0x230\n     ? __pfx_kthread+0x10/0x10\n     ret_from_fork+0x273/0x2b0\n     ? __pfx_kthread+0x10/0x10\n     ret_from_fork_asm+0x1a/0x30","modified":"2026-07-15T01:49:02.339459475Z","published":"2026-05-08T14:22:29.550Z","related":["SUSE-SU-2026:22433-1","SUSE-SU-2026:22436-1","SUSE-SU-2026:22458-1","SUSE-SU-2026:22460-1","SUSE-SU-2026:2722-1","SUSE-SU-2026:2799-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43469.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/49f53ee4e25297d886f14e31f355ad1c2735ddfb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74c39a47856bddcde7874f2196a00143b5cd0af9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7b6275c80a0c81c5f8943272292dfe67730ce849"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7ea69259a60a364f56cf4aa9e2eafb588d1c762b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8127b5fec04757c2a41ed65bca0b3266968efd3b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8cb6b5d8296b1f99a8d36849901ebabfe3f749db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc3ebd7e2d73dbd4d317785735ffa6c4a6384ddf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43469.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43469"},{"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":"15788d1d1077ebe029c48842c738876516d85076"},{"fixed":"7ea69259a60a364f56cf4aa9e2eafb588d1c762b"},{"fixed":"8cb6b5d8296b1f99a8d36849901ebabfe3f749db"},{"fixed":"74c39a47856bddcde7874f2196a00143b5cd0af9"},{"fixed":"49f53ee4e25297d886f14e31f355ad1c2735ddfb"},{"fixed":"8127b5fec04757c2a41ed65bca0b3266968efd3b"},{"fixed":"dc3ebd7e2d73dbd4d317785735ffa6c4a6384ddf"},{"fixed":"7b6275c80a0c81c5f8943272292dfe67730ce849"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43469.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.13.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.130"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.78"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.19"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43469.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
