kernel: netfilter: xt_tcpmss: check remaining length before reading optlen
A flaw was found in the Linux kernel, specifically within the netfilter: xttcpmss module. A remote attacker could exploit this vulnerability by sending a specially crafted TCP packet. The TCP option parser does not properly validate the remaining option length, which results in an out-of-bounds...
CVE-2025-5090
CVE-2025-5090 affects Arista CloudVision Exchange (CVX) in Arista EOS-based deployments. The issue arises when CVX processes unexpected messages from a connected switch, leading to agent crashes on CVX and instability in the CVX cluster, enabling a DoS under high-privilege conditions on the conne...
CVE-2025-5090: Improper Input Validation
CVX is not resilient to unexpected messages from a connected switch. This leads to agent crashes on CVX causing instability in the CVX cluster. An attacker could use this behavior to create a denial of service DoS scenario. Note that this would require the attacker to have a high privilege access...
GHSA-GRGV-6HW6-V9G4 Twisted has a Denial of Service (DoS) in twisted.names via Crafted DNS Compression Pointer Chains
Details The twisted.names module is vulnerable to a Denial of Service DoS attack via resource exhaustion during DNS name decompression. A remote, unauthenticated attacker can exploit this by sending a crafted TCP DNS packet containing deeply chained compression pointers. This flaw bypasses previo...
netavark has incorrect error handling for malformed tcp packets
Impact A truncated TCP DNS query followed by a connection reset causes aardvark-dns to enter an unrecoverable infinite error loop at 100% CPU.
