Astra Linux – Vulnerability in pyasn1

pyasn1 is a generic ASN.1 library for Python. Prior to version 0.6.3, the pyasn1 library was vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion during the decoding of ASN.1 data with deeply nested structures. An attacker could provide a crafted payload containing...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bcache: Fixed the abuse of variable-length arrays in btreeiter. btreeiter is used in two ways: either allocated on the stack with a fixed size MAXBSETS, or from a mempool with a dynamic size based on the specific cache set...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: amd-xgbe: Fixed an issue with the data length underflow in SKB structures. A BUGON will be triggered in the include/linux/skbuff.h file, resulting in intermittent kernel panics when a data length underflow is detected. This...

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

In the Linux kernel, the following vulnerability has been resolved: ALSA: emux: improved patch ioctl data validation. In the loaddata function, the validation of the main information block is performed, while in loadguspatch, this block is skipped. In loadguspatch, additional checks are added to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Firmware: csdsp: Validate the payload length before processing the block. The check for the payload length not exceeding the remaining bytes in the firmware file buffer should be performed before the block is processed. This...

Astra Linux – Vulnerability in Wireshark

In Wireshark versions 3.0.0 to 3.0.3, and 2.6.0 to 2.6.10, the Gryphon dissector could enter an infinite loop. This issue was addressed in the plugin file plugins/epan/gryphon/packet-gryphon.c by checking for a packet length of zero...

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

In the Linux kernel, the following vulnerability has been resolved: ext4: Fixed a double-free of blocks due to incorrect movedlen values during extent movements. In ext4moveextents, movedlen is updated only when all movements are successfully executed. It also discards preallocations of originode...

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

In the Linux kernel, the following vulnerabilities have been resolved: xHCI: Properly handling isoc Babble and Buffer Overrun events. xHCI 4.9 explicitly prohibits making assumptions that the xHC has released its ownership of a multi-TRB TD when an error occurs in one of the early TRBs. However,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfs: Only call foliostartfscache once for each folio. If a network filesystem using netfs implements a clamplength function, it can set subrequest lengths that are smaller than the page size. When we loop through the folios in...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net:emac/emac-mac: A use-after-free issue was addressed in emacmactxbufsend. In emacmactxbufsend, it calls emactxfilltpd.., skb,... If an error occurs in emactxfilltpd, the skb will be freed via devkfreeskbskb in the error branch...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fixed an info leak in hidsubmitctrl. In hidsubmitctrl, the way of calculating the report length does not take into account that report-size can be zero. When running the syzkaller reproducer, a report of size 0 cause...
