CVE-2026-84445

CVE-2026-84445 affects gRPC-Go prior to versions 1.82.2 and 1.83.2 . Servers created via xds.NewGRPCServer() accept RPCs containing neither the :authority nor Host header. The RouteAndProcess function in internal/xds/server/routing.go then assumes an authority value exists and indexes an empty sl...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftpayload: Incorrect arithmetic operations when fetching VLAN header bits. If the offset plus the length exceeds the range of the Ethernet + VLAN header, then the length is adjusted to copy the bytes that are within t...

Astra Linux – Vulnerability in Apache2

The aprwrite function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large inputs using aprwrite or aprputs. This issue can occur, for example, when using the modluas r:puts function. Modules that are compiled and distribute...

Astra Linux – Vulnerability in zlib, libz-mingw-w64

Zlib versions up to 1.2.12 have a heap-based buffer over-read or buffer overflow issue in the inflate function within inflate.c, due to a large gzip header extra field. NOTE: Only applications that call inflateGetHeader are affected. Some common applications bundle the affected Zlib source code,...

Astra Linux – Vulnerability in tar

GNU Tar version 1.34 has a one-byte out-of-bounds read operation that allows for the use of uninitialized memory during a conditional jump. Exploitation to alter the control flow has not been demonstrated. The issue occurs in the fromheader section of the list.c file, due to a V7 archive where...
