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...

sssd: sssd: sudo LDAP provider searches entire directory tree for sudoRole objects by default, enabling privilege escalation

A flaw was found in SSSD's LDAP sudo provider. When the ldapsudosearchbase option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo...
