postgresql: PostgreSQL: Arbitrary code execution via type confusion in cursor lifecycle

A flaw was found in PostgreSQL. This vulnerability, caused by type confusion in the 'portal'/cursor lifecycle, allows a user to execute arbitrary code as the operating system user running the database. This can occur by re-creating a cursor or other portal with different types. Successful...

CVE-2026-89704

A flaw was found in the Linux kernel's nfsd component. The nfsdcopyfilerange function incorrectly samples the writeback error cursor after the copy loop. This allows a concurrent write operation to advance the error cursor prematurely. As a result, the system may report that data has been...
