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: can: peakusb: validate uCAN receive record lengths. The function pcanusbfdDecodeBuf processes uCAN records packed in a single USB receive buffer. It requires that each record contains a fixed header of its own type, and verifies...

Linux network device driver Heap Buffer Overflow DoS

The vulnerability of the ucanprobe function in the drivers/net/can/usb/ucan.c module of the Linux network device driver framework is related to the failure to release resources after their useful life has expired. Exploiting this vulnerability could allow an attacker to cause service failures...

SUSE CVE-2026-74455

In the Linux kernel, the following vulnerability has been resolved: can: peakusb: validate uCAN receive record lengths pcanusbfddecodebuf walks uCAN records packed in one USB receive buffer.

CVE-2026-74455

A flaw was found in the Linux kernel's peakusb Controller Area Network CAN driver. This vulnerability arises from insufficient validation of uCAN receive record lengths when processing data from a Universal Serial Bus USB receive buffer. A local attacker could potentially exploit this by sending...

CVE-2026-46103

A flaw was found in the Linux kernel's can: ucan USB driver. This vulnerability arises from incorrect management of device resource lifetimes, where resources are tied to the parent USB device instead of the USB interface. This can lead to memory leaks when drivers are unbound without the...

AZL-88472 CVE-2026-46103 affecting package kernel for versions less than 6.6.141.1-1

In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers...

CVE-2026-46103

CVE-2026-46103 affects the Linux kernel, specifically the USB stack where can: ucan fixes the devres lifetime. The root cause is that resources bound to USB interfaces were not guaranteed to outlive the parent USB device, leading to memory leaks when drivers unbind (e.g., during probe deferrals o...
