Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: omap: Do not skip resource freeing if pmruntimeresumeandget fails. Returning an error code from .remove causes the driver core to emit a rather useless error message: remove callback returned a non-zero value. This...

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Reinit port-pm on port-specific driver unbind When we unbind a serial port via a hardware-specific 8250 driver, the generic serial8250 driver takes over control of the port. After that, an oops occurs approximately ...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: serial: 8250port: Check IRQ data before use If the leaf driver wishes to use IRQ polling irq = 0, and the IIR register indicates that an interrupt occurred in the 8250 hardware, the IRQ data can be NULL. In such cases, we need to...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

KGDB and KDB allow read and write access to kernel memory, and therefore should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger, so it is important that the debugger respects the lockdown mode when/if it is triggered. CVSS 3.1 Base Score: 6.7...

CVE-2026-68188

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: Fix session UAF in settermios rfcommttysettermios tests dlc-session without rfcommmutex and later passes the pointer to rfcommsendrpn. The latter dereferences both session-initiator and session-sock. Meanwhile,...

Electron: Permission Check Handler Receives Main Frame Origin Instead of Requesting Iframe Origin

Impact For serial-port and media camera / microphone permission checks made from an iframe, the requestingOrigin passed to session.setPermissionCheckHandler was the top-level frame's origin rather than the requesting frame's. Origin-based handler logic could therefore grant a cross-origin iframe...

CVE-2026-70599 Electron: Permission Check Handler Receives Main Frame Origin Instead of Requesting Iframe Origin

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, serial-port and media permission checks made from an iframe passed the top-level frame origin to session.setPermissionCheckHandler instead of...

CVE-2026-63876

A flaw was found in the Linux kernel's zs serial driver. During the initialization of the first serial port, a null pointer dereference occurs when a pointer derived from a null parent device pointer is accessed. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...

Linux Distros Unpatched Vulnerability : CVE-2026-63877

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - serial: dz: Convert to use a platform device Prevent a crash from happening as the first serial port is initialised: Console: switching to colour frame buffer...

SUSE CVE-2026-53384

In the Linux kernel, the following vulnerability has been resolved: serial: 8250dw: unregister 8250 port if clknotifierregister fails dw8250probe registers the 8250 port via serial8250register8250port and then, if the device has a clock, registers a clock notifier. If clknotifierregister fails,...

CVE-2026-63899

CVE-2026-63899 concerns a memory corruption in Linux kernel USB serial mxuport implementation. The vulnerability arises when handling the bulk-out endpoint where the maximum packet size could be smaller than safe, enabling user-controlled slab corruption if a malicious USB device reports a small ...

EUVD-2026-45672

In the Linux kernel, the following vulnerability has been resolved: USB: serial: mxuport: fix memory corruption with small endpoint Make sure that the bulk-out endpoint max packet size is at least eight bytes to avoid user-controlled slab corruption should a malicious device report a smaller size...
