Linux Distros Unpatched Vulnerability : CVE-2026-10658
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - btisorecv in subsys/bluetooth/host/iso.c pulled the ISO SDU header 4 bytes or, when the timestamp flag is set, the timestamped SDU header 8 bytes from the inbou...
CVE-2026-10658: Out-of-bounds Write
A missing length validation in the Zephyr Bluetooth Host ISO receive path can be triggered by malformed HCI ISO data. In btisorecv subsys/bluetooth/host/iso.c, when processing PB=START/SINGLE fragments, the code pulls a TS SDU header 8 bytes, ts=1 or a non-TS SDU header 4 bytes, ts=0 without firs...
CVE-2026-5068: Out-of-bounds Write
A remote, unauthenticated BLE peer can trigger a 2-byte out-of-bounds write in the Bluetooth host during L2CAP LE CoC SDU reassembly. When the application enables segmentation via chanops.allocbuf and the chosen RX pool has a userdatasize smaller than 2 bytes, the segmentation counter stored in t...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: hciconn: now returns ERRPTR instead of NULL when there is no link. Currently, hciconnectsco returns NULL when there is no link i.e., when hciconnlink returns NULL. scoconnect expects ERRPTR in case of any error see...
CVE-2026-43322
A flaw was found in the Bluetooth Host Controller Interface HCI synchronization module hcisync of the Linux kernel. A use-after-free UAF vulnerability exists in the lereadfeaturescomplete function, where a freed hciconn object is accessed. This can allow an attacker to cause a system crash, leadi...
CVE-2026-31772
A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI synchronization. A local user could trigger a stack buffer overflow by binding a specific type of Bluetooth socket with an excessive number of Bluetooth Isochronous Stream BIS entries. This memory corruption can lead t...
