FreeBSD -- Memory safety bugs in kqueue copy-on-fork implementation

Problem Description: When copying knotes from a parent kqueue to a child, the copy code did not correctly exclude marker knotes used internally to track list traversal position before marking them as in-flux and releasing the kqueue lock. If another thread freed a marker while the lock was droppe...

CVE-2026-97547

A flaw was found in the Linux kernel's XFS file system. When exchanging file ranges between files that share storage blocks reflinks, a local user can trigger a condition where the system prematurely clears copy-on-write protection flags from a file that still retains shared data blocks...

DEBIAN-CVE-2026-97335

Incorrect authorization in the custom storage volume creation endpoint in Canonical LXD versions 5.0.0 and later fixed in 5.0.10, 5.21.8 and 6.10 on Linux allows an authenticated client with permission to create custom volumes in a project to copy, and so read, any custom storage volume from any...

postgresql: PostgreSQL psql: Arbitrary command execution via untrusted data in COPY FROM STDIN

A flaw was found in PostgreSQL psql. During the COPY FROM STDIN operation, untrusted data can be mistakenly interpreted as psql commands if an error injection causes the command to fail prematurely. This could allow an attacker to achieve arbitrary command execution. Successful exploitation...
