Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: virtionet: Added a check for hashkeylength. A check for hashkeylength was added in virtnetprobe to avoid possible out-of-bounds errors when setting/read the hash key...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: vpvdpa: fixed the issue where the idtable array was not terminated with a null terminator. Also, an additional virtiodeviceid was allocated as a null terminator. Otherwise, vdpamgmtdevgetclasses might iterate multiple times an...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: added more sanity checks to qdiscpktleninit. One of the approaches handles SKBGSODODGY, assuming that skb-len is greater than hdrlen. The function virtionethdrtoskb does not fully dissect TCP headers; it only ensures that th...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: The initialization of the dangling pointer that occurs in vsk-trans has been addressed. During loopback communication, a dangling pointer can be created in vsk-trans, potentially leading to a Use-After-Free conditio...

In the Linux kernel, the following vulnerability has been resolved: virtionet: Fixed the warning from napibcacheput. After the commit bdacf3e34945 “net: Use nested-BH locking for napialloccache.” was merged, the following warning began to appear: WARNING: CPU: 5 PID: 1 at net/core/skbuff.c:1451...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was detected in the virtio-snd device in QEMU. When reading input audio through the virtio-snd input callback, the virtiosndpcmincb function did not check whether the allocated I/O block could accommodate the data buffer. This issue can lead to an out-of-bounds write if the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: virtio/vsock: Fix acceptqueue memory leak As the final stages of socket destruction may be delayed, it is possible that virtiotransportrecvlisten will be called after the acceptqueue has been flushed, but before the SOCKDONE flag...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: Missing check for virtio Two missing checks in virtionethdrtoskb allowed syzbot to crash kernels again. 1. After the skbsegment function, the buffer may become non-linear nrfrags != 0. However, since the SKBTXSHAREDFRAG...
