| CVE-2025-38232 | 0.00 | — | 0.00 | Jul 4, 2025 | In the Linux kernel, the following vulnerability has been resolved: NFSD: fix race between nfsd registration and exports_proc As of now nfsd calls create_proc_exports_entry() at start of init_nfsd and cleanup by remove_proc_entry() at last of exit_nfsd. Which causes kernel… | |||
| CVE-2024-56779 | 0.00 | — | 0.00 | Jan 8, 2025 | In the Linux kernel, the following vulnerability has been resolved: nfsd: fix nfs4_openowner leak when concurrent nfsd4_open occur The action force umount(umount -f) will attempt to kill all rpc_task even umount operation may ultimately fail if some files remain open.… | |||
| CVE-2024-53073 | 0.00 | — | 0.00 | Nov 19, 2024 | In the Linux kernel, the following vulnerability has been resolved: NFSD: Never decrement pending_async_copies on error The error flow in nfsd4_copy() calls cleanup_async_copy(), which already decrements nn->pending_async_copies. | |||
| CVE-2024-50241 | 0.00 | — | 0.00 | Nov 9, 2024 | In the Linux kernel, the following vulnerability has been resolved: NFSD: Initialize struct nfsd4_copy earlier Ensure the refcount and async_copies fields are initialized early. cleanup_async_copy() will reference these fields if an error occurs in nfsd4_copy(). If they are… | |||

Laundromat thread finds that delegation has… | |||
| CVE-2024-50043 | 0.00 | — | 0.00 | Oct 21, 2024 | In the Linux kernel, the following vulnerability has been resolved: nfsd: fix possible badness in FREE_STATEID When multiple FREE_STATEIDs are sent for the same delegation stateid, it can lead to a possible either use-after-free or counter refcount underflow errors. In… | |||
