The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Bluetooth: hciconn: fix potential UAF in setcigparamssync hciconn lookup and field access must be covered by hdev lock in setcigparamssync, otherwise it's...

Linux Distros Unpatched Vulnerability : CVE-2026-31713

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: fuse: abort on fatal signal during sync init When sync init is used and the server exits for...

CVE-2026-31739

A flaw was found in the Linux kernel's tegra crypto driver. The driver failed to correctly set a flag for its asynchronous cryptographic algorithms. This oversight could lead to the crypto API selecting asynchronous algorithms when a user specifically requests synchronous ones. Consequently, this...

CVE-2026-31713

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. When using synchronous initialization sync init, if the FUSE server exits unexpectedly while processing the FUSEINIT request, the filesystem creation process can hang. This issue occurs because the mounting thread keep...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the unserialize function in the sync-invoke client when processing data received from a server response. An attacker can execute arbitrary code by sending crafted serialized data from a malicious...

CVE-2026-43019

A flaw was found in the Linux kernel's Bluetooth component. Improper synchronization in the setcigparamssync function can lead to a use-after-free UAF vulnerability. This issue arises when hciconn objects are accessed without proper locking, allowing them to be freed concurrently. An attacker cou...

CVE-2026-43021

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: fix leaks when hcicmdsyncqueueonce fails When hcicmdsyncqueueonce returns with error, the destroy callback will not be called. Fix leaking references / memory on these failures...

CVE-2026-31772

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: fix stack buffer overflow in hcilebigcreatesync hcilebigcreatesync uses DEFINEFLEX to allocate a struct hcicplebigcreatesync on the stack with room for 0x11 17 BIS entries. However, conn-numbis can hold up to...

CVE-2026-43022

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hcicmdsyncqueueonce return -EEXIST if exists hcicmdsyncqueueonce needs to indicate whether a queue item was added, so caller can know if callbacks are called, so it can avoid leaking resources. Change the...

CVE-2026-43022

The CVE-2026-43022 issue affects the Linux kernel Bluetooth HCI synchronization path: hci_cmd_sync_queue_once() did not indicate when a queue item already existed, risking resource leaks. The fix changes hci_cmd_sync_queue_once() to return -EEXIST when a queue item already exists and requires upd...

CVE-2026-31772

The CVE-2026-31772 issue affects the Linux kernel Bluetooth HCI path. The root cause is a stack buffer overflow in hci_le_big_create_sync where DEFINE_FLEX allocates a stack struct for BIS entries with room for 17, but conn->num_bis can be up to 31, leading to a memcpy that can write beyond th...
