Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Do not redirect packets with invalid pktlen Syzbot identified an issue 1: the fqcodel Drop function attempts to drop a flow without any SKBs, that is, when flow-head is null. The root cause, as stated in 2, is that the...

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

In the Linux kernel, the following vulnerability has been resolved: usb: aqc111: Check the packet for fixup for true limits. If a device sends a packet that lies between 0 and sizeofu64, the value passed to skbtrim as the packet length will wrap around, resulting in a very large value. The driver...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, 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 length of the packet header is validated before calling skbPut. When receiving a vsock packet in the guest, only the size of the virtqueue buffer is validated prior to calling virtiovsockskbrxPut. Unfortunately,...

Astra Linux – Vulnerability in libslirp

In ncsi.c within libslirp up to 4.3.1, there is an issue of buffer over-reading. This occurs because the program attempts to read a certain amount of header data, even when that amount exceeds the total packet length...

EUVD-2026-75363

A heap-based buffer overflow vulnerability in the PC bridge protocol decoder of BoschSensortec COINESSDK versions 2.10 through 2.12.2 allows attackers to cause a denial of service process crash or potentially execute arbitrary code. The bridge decoder bridgedecoder.c trusts the packet length fiel...

EUVD-2026-70800

MOOS core-moos through 10.4.0 contains a pre-authentication heap overflow vulnerability in MOOSCommPkt packet handling that allows remote attackers to write arbitrary data by declaring a negative packet length. Attackers can exploit the signed integer check in InflateTo and negative size conversi...
