CVE-2026-53397
A flaw was found in the Linux kernel's Network File System Daemon nfsd. This vulnerability occurs during the processing of Access Control List ACL set operations. If a specific decode step fails, a memory leak of a posixacl object occurs. This can lead to resource exhaustion over time, potentiall...
CVE-2026-53396
A flaw was found in the Linux kernel's Network File System NFS daemon nfsd within the nfsd4createfile function. This vulnerability allows a remote attacker to cause a denial of service DoS by repeatedly triggering a memory leak of posixacl allocations. The leak occurs when a client attempts to...

CVE-2026-64139
CVE-2026-64139 : In the Linux kernel ksmbd path, a memory-leak exists in set_posix_acl_entries_dacl() on overflow. The loop allocates a struct smb_sid with kmalloc_obj() each iteration and relies on per-iteration kfree() at loop end. Introduced break paths skip these frees, causing the sid buffer...

CVE-2026-53397
The CVE-2026-53397 entry describes a Linux kernel leakage with posix_acl objects during SETACL decode in NFS code paths. Specifically, nfsaclsvc_decode_setaclargs() and nfs3svc_decode_setaclargs() call nfs_stream_decode_acl() for NFS_ACL and NFS_DFACL; if the first succeeds and the second fails, ...
