In the Linux kernel, the following vulnerability has been resolved: USB: usbtmc: Fixed the direction of 0-length ioctl control messages The syzbot fuzzer identified a issue with the usbtmc driver: When a user sends an ioctl with a 0-length control transfer, the driver does not check whether the...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mmc: vub300 – Fixed the return value check in mmcaddhost. If we ignore the return value of mmcaddhost, the memory allocated in mmcallochost may be leaked, leading to a kernel crash due to the removal of devices that were not...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: asix: Proper error handling for USB read errors has been added. The Syzbot issue with the asix driver remains the same. The problem is still present—the asixreadcmd function reads fewer bytes than requested by the caller...

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: typec: bus: verify partner exists in typecaltmodeattention Some USB hubs will negotiate DisplayPort Alt mode with the device. However, they will then negotiate a data role swap after entering the Alt mode. This data role swa...

Astra Linux – Vulnerability in Chromium

In Google Chrome versions prior to 88.0.4324.96, uninitialized usage in USB devices allowed a local attacker to potentially perform out-of-bound memory access through a USB device...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: fixed the issue of null pointer dereferencing on the pointer csdesc. The pointer csdesc is returned from sndusbfindclocksource; this pointer may be null, resulting in a potential null pointer dereferencing issue...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: - usb: dwc2: gadget: Fixed the mismatch between spinlock and unlock calls in dwc2hsotgudcstop. - dwc2gadgetexitclockgating: Internally calls the callgadget macro, which expects hsotg-lock to be held since it performs...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: USB: isp1362 – A memory leak was fixed by using debugfslookup. When calling debugfslookup, the result must be processed with dput, otherwise a memory leak will occur over time. To simplify things, simply call...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Input: aiptek – properly checking the endpoint type Syzbot reported a warning in usbsubmiturb, which is caused by an incorrect endpoint type. There was a check for the number of endpoints, but not for the type of endpoints. The...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read without sufficient bounds checking, assuming that the USB device provides valid values. If exploited properly, an attacker could cause memory corruption, leading to arbitrary code...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: media: zr364xx: fixed a memory leak in zr364xxstartreadpipe syzbot reported a memory leak in the zr364xx driver. The issue occurred when non-free urb occurred in case of a failure in usbsubmiturb. Backtrace: kmalloc...

Astra Linux – Vulnerability in opensc

A heap-based buffer overflow vulnerability was discovered in the libopensc OpenPGP driver. A specially crafted USB device or smart card, containing malicious responses to APDUs during the card enrollment process using the pkcs15-init tool, may lead to unauthorized access, potentially resulting in...
