CVE-2026-63814 f2fs: validate ACL entry sizes in f2fs_acl_from_disk()

In the Linux kernel, the following vulnerability has been resolved: f2fs: validate ACL entry sizes in f2fsaclfromdisk f2fsaclcount only validates the aggregate ACL xattr length. A malformed ACL can still place ACLUSER or ACLGROUP in a slot that only contains struct f2fsaclentryshort bytes, and...

CVE-2026-63814

CVE-2026-63814 (Linux kernel, f2fs) is resolved. A malformed ACL in f2fs_acl_from_disk() could bypass proper length checks because f2fs_acl_count() only validates the aggregate ACL xattr length, allowing ACL_USER/ACL_GROUP entries to be read before a full entry fits. The fix adds checks: require ...

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix posixacl leak on SETACL decode failure nfsaclsvcdecodesetaclargs and nfs3svcdecodesetaclargs each call nfsstreamdecodeacl twice, first for NFSACL and then for NFSDFACL. Each successful call transfers ownership of a...

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, ...
