EUVD-2026-55546

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

The CVE-2026-68160 vulnerability affects Ceph in the Linux kernel where ceph_handle_caps() reads snap_trace_len from the wire-format and uses it to compute snaptrace + snaptrace_len before validation. If msg->hdr.version is 1 (no decoder validation), an attacker-controlled snap_trace_len can d...

EUVD-2026-55529

In the Linux kernel, the following vulnerability has been resolved: iomap: fix out-of-bounds bitmapset with zero-length range ifssetrangedirty and ifssetrangeuptodate compute lastblk as off + len - 1 iblkbits. When off is 0 and len is 0, the unsigned subtraction underflows to SIZEMAX, producing a...

CVE-2026-68145

Summary: The CVE affects the Linux kernel iomap path, specifically the functions ifs_set_range_dirty() and ifs_set_range_uptodate() . The root cause is the calculation of the last block as (off + len - 1) >> i_blkbits. When off is 0 and len is 0, unsigned subtraction underflows to SIZE_MAX,...

In the Linux kernel, the following vulnerability has been resolved: mac802154: llsec: reject frames shorter than the authentication tag llsecdodecryptauth computes the associated-data length for the AEAD request as assoclen += datalen - authlen; where datalen is the number of bytes after the MAC...

CVE-2026-68125 mac802154: llsec: reject frames shorter than the authentication tag

In the Linux kernel, the following vulnerability has been resolved: mac802154: llsec: reject frames shorter than the authentication tag llsecdodecryptauth computes the associated-data length for the AEAD request as assoclen += datalen - authlen; where datalen is the number of bytes after the MAC...

CVE-2026-68124 mctp: serial: handle zero-length frames to prevent rx buffer overflow

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

CVE-2026-68124

Summary (CVE-2026-68124): In the Linux kernel’s MCTP serial path (mctp_serial_tty_receive_buf), a zero-length frame could cause an out-of-bounds heap write when rxlen is 0 and the parser enters STATE_DATA, allowing attacker-controlled writes after CAP_NET_ADMIN attaches the mctpserial netdev. The...

EUVD-2026-55504

In the Linux kernel, the following vulnerability has been resolved: openvswitch: fix GSO userspace truncation underflow OVSACTIONATTRTRUNC currently stores a delta from the original skb length in OVSCBskb-cutlen. When a later userspace action segments a GSO skb, queuegsopackets reuses that delta...

CVE-2026-68123

Open vSwitch vulnerability CVE-2026-68123 concerns GSO truncation underflow in the Linux kernel’s handling of OVS_ACTION_ATTR_TRUNC. The issue arises when a later userspace action segments a GSO skb and reuses the delta stored in OVS_CB(skb)->cutlen for each segment, which can lead to a cutlen...

CVE-2026-68107 drm/amdgpu/vcn4: avoid rereading IB param length

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: avoid rereading IB param length Reuse the parameter length returned by vcnv40encfindibparam instead of rereading it from the IB. This avoids a potential TOCTOU issue if the IB contents change between reads. cherr...

CVE-2026-68107

CVE-2026-68107 affects the Linux kernel’s DRM AMDGPU VCN4 path. The issue arises from rereading the IB parameter length; the fix reuses the length returned by vcn_v4_0_enc_find_ib_param() instead of re-reading it from the IB, thereby preventing a TOCTOU condition if IB contents change between rea...
