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

In the Linux kernel, the following vulnerability has been resolved: usb: cdc-acm: Check the control transfer buffer size before accessing it. If the first fragment is shorter than struct usbcdcnotification, we cannot calculate the expectedsize. Instead, log an error and discard the notification...

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

In the Linux kernel, the following vulnerability has been resolved: USB: class: cdc-wdm: Fixed the CPU lockup caused by excessive log messages. The syzbot fuzzer found that the interrupt-URB completion callback in the cdc-wdm driver took too long. The driver’s immediate resubmission of interrupts...
