CVE-2026-67198

Perspective 5.0.0 contains a denial-of-service vulnerability in the VirtualServer protocol dispatcher that allows unauthenticated remote attackers to crash the server process by sending malformed or incomplete protobuf messages. Attackers can send well-formed requests such as ViewToArrowReq with ...

UEFI Firmware Parser has a stack out-of-bounds write in tiano decompressor MakeTable

uefi-firmware contains a stack out-of-bounds write vulnerability in the native tiano/EFI decompressor. in uefifirmware/compression/Tiano/Decompress.c, MakeTable does not validate that bit-length values read from the compressed bitstream are within the expected range 0..16. a crafted firmware blob...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write through the MakeTable in the decompression routine when bit-length values from a crafted firmware blob exceed the expected range, leading to stack memory corruption in the Count array and related decode tables. An...

Important: edk2

Issue Overview: A missing check leads to an out-of-bounds read and write flaw in NetworkPkg/DnsDxe as shipped in edk2, when it parses DNS responses. A remote attacker who controls the DNS server used by the vulnerable firmware may use this flaw to make the system crash. CVE-2018-3613 improper DNS...

edk2: Privilege escalation via stack-based buffer overflow in MakeTable() function

REJECTED CVE A stack-based buffer overflow vulnerability was identified in EDK-2 within the MakeTable function of BaseUefiDecompressLib.c, TianoCompress.c, and the UEFI specification. An authenticated attacker could exploit this vulnerability by supplying a crafted file, potentially leading to...
