Hands-on Firmware Extraction, Exploration, and Emulation Join us for this hands-on demo of Unblob, the flexible firmware extractor. During this workshop session, we will extract firmware from an EV charger, dig into the firmware, and eventually emulate it so we can interact with the services in...

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

A issue was discovered in the Linux kernel before version 6.2.9. A use-after-free was found in the bq24190remove function in the file drivers/power/supply/bq24190charger.c. This could allow a local attacker to cause the system to crash due to a race condition...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: phy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered The powersupply framework is not actually designed to have long references to powersupply devices in the kernel. Specifically, unregistering a powersuppl...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: power: supply: cpcap-charger: Fixed the null check for powersupplygetbyname. In the cpcapusbdetect function, the powersupplygetbyname function may return NULL instead of an error pointer. To prevent potential null pointer...

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

The Linux kernel before version 6.2.9 has a race condition, which can lead to a use-after-free issue in the driver/power/supply/da9150-charger.c file. This issue occurs when a physically nearby attacker disconnects a device...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Power: Supply: gpio-charger: Fixed the issue related to setting charge current limits. The issue involved devices that allow the lowest charge current limit to be greater than zero. If the requested charge current limit is below...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: usb: chipidea: cihdrcimx: Also search for ‘phys’ handle. When passing ‘phys’ in the device tree to describe the USB PHY handle which is the recommended approach according to Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt,...

CVE-2026-89470

A flaw was found in the Linux kernel's crosusbpd-charger driver. This driver, which manages USB power delivery, incorrectly processes port count information from an embedded controller. A malicious embedded controller could provide an exaggerated port count, leading to an out-of-bounds write and...

Linux Distros Unpatched Vulnerability : CVE-2026-89471

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - power: supply: crosusbpd-charger: bound the EC-reported port count crosusbpdchargerprobe reads two port counts from the EC and uses one of them, numchargerports...

CVE-2026-89471

A flaw was found in the Linux kernel's crosusbpd-charger driver. A malicious or compromised embedded controller EC can report an excessive number of USB Power Delivery PD ports. This causes the driver to write beyond the allocated memory buffer when populating a fixed-size array for port data,...

CVE-2026-89474

A flaw was found in the Linux kernel's power supply subsystem, specifically within the bq256xx driver. This vulnerability occurs when a USB work item attempts to access a charger object after it has been freed. This timing issue can lead to a use-after-free condition, potentially causing system...

CVE-2026-89468

A flaw was found in the Linux kernel's lp8788-charger component. During the removal of the lp8788-charger, a race condition can occur where work can be queued and executed after the associated memory has been freed. This use-after-free vulnerability could lead to system instability or a denial of...

CVE-2026-89472

A flaw was found in the Linux kernel's power supply charger-manager component. A race condition exists where the system frees charger regulators before their corresponding sysfs entries are unregistered. A local attacker can exploit this by performing a concurrent write to a charger's...

DEBIAN-CVE-2026-89471

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd-charger: bound the EC-reported port count crosusbpdchargerprobe reads two port counts from the EC and uses one of them, numchargerports, as the loop bound when populating a fixed-size array: struct portda...
