CVE-2026-73447: Improper Neutralization of Special Elements used in an OS Command

A privileged attacker can exploit certain operation to execute arbitrary commands with root privileges, leading to full device compromise. An authenticated user can exploit gRPC Network Security Interface gNSI Certz service on Arista EOS-based products to escalate privileges and execute arbitrary...

CVE-2026-73454: Improper Neutralization of Special Elements used in a Command

On affected platforms running Arista EOS with gRPC Network Security Interface gNSI Credentialz configured, a specially crafted request can cause unintended modifications to the target account's properties. This may result in the account being assigned elevated privileges or access beyond what an...

CVE-2026-73445: Improper Input Validation

On affected platforms running Arista EOS, an issue with the gRPC Network Security Interface gNSI Authz Rotate RPC may cause an incorrect Authz policy which was uploaded in the ongoing RPC stream to become active. This does not affect Bootz. This issue was discovered internally by Arista and the...

firewalld: firewalld: Local unprivileged user can modify firewall state due to D-Bus setter mis-authorization

A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus Desktop Bus setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication,...

CVE-2026-45769

A flaw was found in Suricata, a network Intrusion Detection System IDS, Intrusion Prevention System IPS, and Network Security Monitoring engine. A remote attacker can exploit this vulnerability by sending repeated crafted User Datagram Protocol UDP traffic to the IKEv2 parser. This can cause the...

CVE-2026-76682: Buffer Copy without Checking Size of Input

A vulnerability in the network security monitoring component of intrusion detection systems could allow an unauthenticated remote attacker to exploit a limited buffer overflow. Successful exploitation could allow an attacker to cause a denial-of-service or potentially execute arbitrary code on th...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, NSS

A mismatch between the allocator and deallocator could have led to memory corruption. This vulnerability affects Firefox 128, Firefox ESR 115.13, Thunderbird 115.13, and Thunderbird 128...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, NSS

An unchecked return value in the TLS handshake code could have caused a potentially exploitable crash. This vulnerability affects Firefox 122, Firefox ESR 115.9, and Thunderbird 115.9...

Astra Linux – Vulnerability in nss

A flaw was discovered in the way NSS handled CCS ChangeCipherSpec messages in TLS 1.3. This flaw allows a remote attacker to send multiple CCS messages, resulting in a denial of service for servers compiled with the NSS library. The greatest threat posed by this vulnerability is related to system...

Astra Linux – Vulnerability in nss

During RSA key generation, bignum implementations used a variant of the Binary Extended Euclidean Algorithm, which involved significant input-dependent processes. This allowed attackers to perform electromagnetic-based side-channel attacks to capture traces that could lead to the recovery of secr...

Astra Linux – Vulnerability in nss

NSS has demonstrated timing differences during the execution of DSA signatures, which can be exploited and may eventually lead to the leakage of private keys. This vulnerability affects Thunderbird versions 68.9.0, Firefox versions 77, and Firefox ESR versions 68.9...

Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...

Astra Linux – Vulnerability in Linux

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP does not require that all fragments of a frame be encrypted with the same key. An adversary can exploit this weakness to decrypt selected fragments when another device sends fragmented...

PT-2026-91690

A certificate validation issue was addressed with improved certificate validation. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. An attacker in a privileged network position may be able to intercept network traffic...

CVE-2026-90996: Integer Underflow (Wrap or Wraparound)

A flaw was found in sssd. A local unprivileged user could send a specially crafted request with a zero-length body to the Network Security Services NSS responder. This could lead to a denial-of-service condition, causing the NSS responder to become unstable or terminate. This vulnerability affect...

Linux Distros Unpatched Vulnerability : CVE-2026-45751

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5,...

DEBIAN-CVE-2026-45769

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5,IKEv2 parser state could grow without bounds while storing client transforms. Repeated crafted UDP traffic may cause Suricata to consume excessi...

EUVD-2026-75767

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, certain NFS parser state structures were insufficiently bounded. Crafted NFS traffic may cause Suricata to consume excessive memory, potentiall...

CVE-2026-46387 Suricata http2: decompression bomb can cause denial of service in Suricata

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, Suricata's HTTP/2 decompression path could grow the decompressed response-body buffer without an effective upper bound. A crafted HTTP/2 DATA...
