In the Linux kernel, the following vulnerability has been resolved: virtio-net: The issue of checking the received length in large packets has been fixed. Since commit 4959aebba8c0 “virtio-net: Use the MTU size as the buffer length for large packets”, when the guest gso is disabled, the allocated...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: Do not exceed the ARM processor CPER record buffer. There is a logic within GHES/CPER that detects whether the sectionlength is too small, but it does not detect whether it is too large. Currently, if the firmware...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: RDMA/umad: Reject negative datalen in ibumadwrite ibumadwrite calculates datalen based on a user-controlled count and the MAD header sizes. When the user-defined MAD header size does not match the RMPP header length, datalen can...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Wifi: rtl818x: rtl8187: A potential buffer underflow has been fixed in rtl8187rxcb. The rtl8187rxcb function calculates the RX descriptor header address by subtracting its size from the skbtailptr. However, it does not validate...

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...

In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: fixed a potential buffer overflow in i2chidgetreport i2chidxfer is used to read recvlen + sizeofle16 bytes of data into ihid-rawbuf. The former can originate from the user space of the hidraw driver and is bounded b...

Astra Linux – Vulnerability in pyopenssl

pyOpenSSL is a Python wrapper around the OpenSSL library. Starting from version 22.0.0 and before version 26.0.0, if a user provided a callback for setcookiegeneratecallback and the returned cookie value was longer than 256 bytes, pyOpenSSL would cause an overflow of the buffer provided by OpenSS...
