When that happens, the call\nto put_nfs_open_context() can trigger a synchronous delegreturn call\nwhich deadlocks because it is not marked as privileged.\n\nInstead, ensure that the call to nfs4_inode_return_delegation_on_close()\ncatches the delegreturn, and schedules it asynchronously.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00355,"percentile":0.29475,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-667"],"published":"2025-04-01T15:26:51Z","modified":"2026-10-30T21:55:24Z","fixes":[{"ecosystem":"Alpaquita:25","package":"linux-lts","fixed_in":["6.12.41-r0"],"sources":["osv"]},{"ecosystem":"Alpaquita:stream","package":"linux-lts","fixed_in":["6.18.35-r1"],"sources":["osv"]},{"ecosystem":"Linux","package":"Kernel","fixed_in":["6.12.18","6.13.6"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"linux","fixed_in":["6.12.19-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"linux","fixed_in":["6.12.19-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"linux-azure-6.11","fixed_in":["6.11.0-1015.15~24.04.1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"linux-gcp-6.11","fixed_in":["6.11.0-1015.15~24.04.1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"linux-hwe-6.11","fixed_in":["6.11.0-26.26~24.04.1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"linux-lowlatency-hwe-6.11","fixed_in":["6.11.0-1014.15~24.04.1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"linux-nvidia-6.11","fixed_in":["6.11.0-1010.10"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"linux-oem-6.11","fixed_in":["6.11.0-1022.22"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpaquita:25","package":"linux-lts","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.89-r0"},{"fixed":"6.12.41-r0"}]}]},{"source":"osv","ecosystem":"Alpaquita:stream","package":"linux-lts","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.92-r1"},{"fixed":"6.18.35-r1"}]}]},{"source":"osv","ecosystem":"Linux","package":"Kernel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.12.18"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.13.6"}]}]},{"source":"osv","ecosystem":"Debian:13","package":"linux","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.19-1"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"linux","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.19-1"}]}]},{"source":"osv","ecosystem":"Ubuntu:16.04:LTS","package":"linux-hwe-edge","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.8.0-28.30~16.04.1","4.8.0-30.32~16.04.1","4.8.0-32.34~16.04.1","4.8.0-34.36~16.04.1","4.10.0-14.16~16.04.1","4.10.0-19.21~16.04.1","4.10.0-20.22~16.04.1","4.10.0-21.23~16.04.1","4.10.0-22.24~16.04.1","4.10.0-24.28~16.04.1","4.10.0-26.30~16.04.1","4.11.0-13.19~16.04.1","4.11.0-14.20~16.04.1","4.13.0-16.19~16.04.3","4.13.0-17.20~16.04.1","4.13.0-19.22~16.04.1","4.13.0-21.24~16.04.1","4.13.0-25.29~16.04.2","4.15.0-13.14~16.04.1","4.15.0-15.16~16.04.1","4.15.0-20.21~16.04.1","4.15.0-22.24~16.04.1","4.15.0-23.25~16.04.1"]},{"source":"osv","ecosystem":"Ubuntu:18.04:LTS","package":"linux-aws-5.0","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-1021.24~18.04.1","5.0.0-1022.25~18.04.1","5.0.0-1023.26~18.04.1","5.0.0-1024.27~18.04.1","5.0.0-1025.28","5.0.0-1027.30"]},{"source":"osv","ecosystem":"Ubuntu:18.04:LTS","package":"linux-aws-5.3","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.3.0-1016.17~18.04.1","5.3.0-1017.18~18.04.1","5.3.0-1019.21~18.04.1","5.3.0-1023.25~18.04.1","5.3.0-1028.30~18.04.1","5.3.0-1030.32~18.04.1","5.3.0-1032.34~18.04.2","5.3.0-1033.35","5.3.0-1034.36","5.3.0-1035.37"]},{"source":"osv","ecosystem":"Ubuntu:18.04:LTS","package":"linux-azure","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.15.0-1002.2","4.15.0-1003.3","4.15.0-1004.4","4.15.0-1008.8","4.15.0-1009.9","4.15.0-1012.12","4.15.0-1013.13","4.15.0-1014.14","4.15.0-1018.18","4.15.0-1019.19","4.15.0-1021.21","4.15.0-1022.23","4.15.0-1023.24","4.15.0-1025.26","4.15.0-1028.29","4.15.0-1030.31","4.15.0-1031.32","4.15.0-1032.33","4.15.0-1035.36","4.15.0-1036.38","4.15.0-1037.39","4.18.0-1011.11~18.04.1","4.18.0-1013.13~18.04.1","4.18.0-1014.14~18.04.1","4.18.0-1018.18~18.04.1","4.18.0-1019.19~18.04.1","4.18.0-1020.20~18.04.1","4.18.0-1023.24~18.04.1","4.18.0-1024.25~18.04.1","4.18.0-1025.27~18.04.1","5.0.0-1014.14~18.04.1","5.0.0-1016.17~18.04.1","5.0.0-1018.19~18.04.1","5.0.0-1020.21~18.04.1","5.0.0-1022.23~18.04.1","5.0.0-1023.24~18.04.1","5.0.0-1025.27~18.04.1","5.0.0-1027.29~18.04.1","5.0.0-1028.30~18.04.1","5.0.0-1029.31~18.04.1","5.0.0-1031.33","5.0.0-1032.34","5.0.0-1035.37","5.0.0-1036.38"]},{"source":"osv","ecosystem":"Ubuntu:18.04:LTS","package":"linux-azure-5.3","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.3.0-1007.8~18.04.1","5.3.0-1008.9~18.04.1","5.3.0-1009.10~18.04.1","5.3.0-
