Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: caif: Fixed integer underflow in cffrmlreceive. The cffrmlreceive function extracts a length field from the packet header. When FCS is disabled, it subtracts 2 from this length without verifying that len is greater than or equal ...

The vulnerability of the cffrml_receive() function in the Linux operating system allows a hacker to gain unauthorized access to protected information or cause service failures.

The vulnerability of the cffrmlreceive function in the Linux operating system is related to a numerical reduction in significance. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information or cause service failures...
