CVE-2022-4543 NOMISEC MEDIUM WORKING POC
Linux Kernel - KASLR Base Leak via EntryBleed TLB Prefetch Side-Channel
A flaw named "EntryBleed" was found in the Linux Kernel Page Table Isolation (KPTI). This issue could allow a local attacker to leak KASLR base via prefetch side-channels based on TLB timing for Intel systems.
CVSS 5.5
CVE-2022-27666 NOMISEC HIGH STUB
Linux Kernel < 5.17 - Heap Buffer Overflow in IPsec ESP Transformation
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
CVSS 7.8
CVE-2026-27940 NOMISEC HIGH STUB
llama.cpp <b8146 - Memory Corruption
llama.cpp is an inference of several LLM models in C/C++. Prior to b8146, the gguf_init_from_file_impl() in gguf.cpp is vulnerable to an Integer overflow, leading to an undersized heap allocation. Using the subsequent fread() writes 528+ bytes of attacker-controlled data past the buffer boundary. This is a bypass of a similar bug in the same file - CVE-2025-53630, but the fix overlooked some areas. This vulnerability is fixed in b8146.
CVSS 7.8
CVE-2021-3156 NOMISEC HIGH STUB
Sudo Heap-Based Buffer Overflow
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character.
CVSS 7.8
CVE-2022-0324 NOMISEC HIGH WORKING POC
SONiC DHCPv6 Relay - Remote Denial of Service via Malformed DHCPv6 Packet
There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp relay docker to shutdown. Discovered by Eugene Lim of GovTech Singapore.
CVSS 8.1
CVE-2019-13288 NOMISEC MEDIUM WRITEUP
Glyphandcog Xpdfreader - Denial of Service
In Xpdf 4.01.01, the Parser::getObj() function in Parser.cc may cause infinite recursion via a crafted file. A remote attacker can leverage this for a DoS attack. This is similar to CVE-2018-16646.
CVSS 5.5
CVE-2022-29800 NOMISEC MEDIUM WORKING POC
Windows Defender for Endpoint - Time-of-check Time-of-use Race Condition
A time-of-check-time-of-use (TOCTOU) race condition vulnerability was found in networkd-dispatcher. This flaw exists because there is a certain time between the scripts being discovered and them being run. An attacker can abuse this vulnerability to replace scripts that networkd-dispatcher believes to be owned by root with ones that are not.
