CVE-2026-68160 ceph: fix pre-auth out-of-bounds read on snaptrace in ceph_handle_caps()

In the Linux kernel, the following vulnerability has been resolved: ceph: fix pre-auth out-of-bounds read on snaptrace in cephhandlecaps cephhandlecaps reads snaptracelen from the wire-format cephmdscaps header and uses it unconditionally to build a fake end pointer snaptrace + snaptracelen that ...

CVE-2026-68160

Summary: CVE-2026-68160 is a pre-auth, out-of-bounds read vulnerability in the Linux kernel’s Ceph code path (ceph_handle_caps) caused by using attacker-controlled snap_trace_len to compute an end pointer without proper bounds checks. The issue can lead to out-of-bounds reads of encoded snap data...

PT-2026-69560

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A pre-authentication out-of-bounds read exists in the ceph handle caps function. The issue occurs because the function reads the snap trace len variable from the ceph mds caps header and...

CVE-2026-46024

In the Linux kernel, the following vulnerability has been resolved: libceph: Prevent potential null-ptr-deref in cephhandleauthreply If a message of type CEPHMSGAUTHREPLY contains a zero value for both protocol and result, this is currently not treated as an error. In case of ac-negotiating == tr...

CVE-2026-46024

CVE-2026-46024 targets the Linux kernel libceph component, where a CEPH_MSG_AUTH_REPLY containing zero values for both protocol and result could lead to a null pointer dereference due to ac->ops being NULL after faulty auth handling. The root cause is that a too-permissive check allowed ac-&gt...

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...
