Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The rcubarrier function was called in ksmbdserverexit. The bug is triggered due to racing between closing a connection and the rmmod operation. In ksmbd, rcubarrier is not called at the time of module unloading, so nothing...

Astra Linux – Vulnerability in node-get-func-name

get-func-name is a module that securely and consistently retrieves the name of a function, both in Node.js and in the browser. Versions prior to 2.0.1 are vulnerable to a denial-of-service attack caused by regular expressions, which can lead to a denial of service when parsing malicious input. Th...

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: Avoid using the nfcthelperhash after the free operation. If the nfconntrackinitstart function fails e.g., due to a registernfconntrackbpf failure, the nfconntrackhelperfini cleanup routine frees the...

Astra Linux – Vulnerability in sane-backends

A out-of-bounds read in SANE backends before version 1.0.30 may allow a malicious device connected to the same local network as the victim to read important information, such as the ASLR offsets of the program, also known as GHSL-2020-081...

Astra Linux – Vulnerability in Qemu

A potential stack overflow issue due to an infinite loop was identified in various NIC emulators of QEMU, in versions up to and including 5.2.0. The issue occurs in the loopback mode of a NIC, where reentrant DMA checks are bypassed. A guest user/process may exploit this flaw to consume CPU cycle...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/smc: Fixed a possible leak of the pernet namespace in smcinit. In smcinit, registerpernetsubsys&smcnetstatops is called without any error handling. If this call fails, the registration of &smcnetops will not be reversed. And ...

Astra Linux – Vulnerability in Qemu

In QEMU versions up to 8.0.0, a division by zero can occur in the scsidiskreset function in hw/scsi/scsi-disk.c. This occurs because scsidiskemulatemodeselect does not prevent the s-qdev blocksize from being 256. This causes QEMU and the guest to stop functioning immediately...

Astra Linux – Vulnerability in Qemu
