CVE-2026-80954

A flaw was found in the Linux kernel's i3c driver. The i3cdevicegetsupportedxfermode function attempts to access a device descriptor without holding the necessary lock. This unlocked dereference can lead to memory corruption, potentially causing system instability or a denial of service...

CVE-2026-89609

A flaw was found in the eCryptfs component of the Linux kernel. A race condition occurs during the cleanup of the daemon message queue because a required lock is not held. This can lead to unpredictable system behavior or instability due to concurrent access to shared message context lists...

EUVD-2026-76480

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: serialize security confirmation handling rfcommsecuritycfm looks up a session on sessionlist and then walks its DLC list without holding rfcommmutex. Since RFCOMM session teardown uses rfcommmutex, krfcommd can...

CVE-2026-89508

The Linux kernel RDMA/ucma subsystem contains a race condition in ucma_set_ib_path(), which calls ucma_event_handler() from the write path without acquiring the handler lock. A concurrent ucma_migrate_id() can reassign ctx->file between mutex operations, causing list_add_tail() to target a dif...

CVE-2026-80954 i3c: Fix unlocked dereference of dev->desc in i3c_device_get_supported_xfer_mode()

In the Linux kernel, the following vulnerability has been resolved: i3c: Fix unlocked dereference of dev-desc in i3cdevicegetsupportedxfermode i3cdevicegetsupportedxfermode uses dev-desc to obtain the master controller. However, dev-desc must not be dereferenced unless bus-lock is held, and this...

CVE-2026-80954

CVE-2026-80954 affects the Linux kernel I3C subsystem . The function i3c_device_get_supported_xfer_mode() dereferences dev->desc to obtain the master controller without holding the required bus->lock, creating a use-after-free or race condition risk. The fix replaces the dev->desc access...

Tak...

kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp

A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP implementation. A remote Bluetooth Low Energy BLE device can exploit this by sending a specially crafted L2CAP ECRED reconfiguration response. This can lead to the corruption of the channel list,...

kernel: smb: client: protect tc_count increment in smb2_find_smb_sess_tcon_unlocked()

A flaw was found in the Linux kernel's Server Message Block SMB client. A missing lock around the tccount increment in the smb2findsmbsesstconunlocked function creates a race condition. This vulnerability, caused by an incomplete refactoring of locking mechanisms, could lead to unexpected behavio...
