CVE-2026-43407

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in cephhandleauthreply This patch fixes an out-of-bounds access in cephhandleauthreply that can be triggered by a message of type CEPHMSGAUTHREPLY. In cephhandleauthreply, the value of...

CVE-2026-43407

The CVE-2026-43407 issue affects the Linux kernel libceph component, where a CEPH_MSG_AUTH_REPLY with a large payload_len could trigger an integer overflow and out-of-bounds read. The root cause is storing payload_len and related lengths in int, allowing negative values to underflow pointers. The...

CVE-2026-43389 mm: memfd_luo: always dirty all folios

In the Linux kernel, the following vulnerability has been resolved: mm: memfdluo: always dirty all folios A dirty folio is one which has been written to. A clean folio is its opposite. Since a clean folio has no user data, it can be freed under memory pressure. memfd preservation with LUO saves t...

CVE-2026-43389

CVE-2026-43389 affects the Linux kernel memfd_luo subsystem. The root cause is a flaw where preserving LUO state could leave folios marked clean, risking data loss if they are dirtied later and reclaimed under memory pressure. The fix changes all folios of the file to be dirty and sets MEMFD_LUO_...
