CVE-2023-49062: Katran could disclose non-initialized kernel memory as part of an IP header. The issue was present for IPv4 encapsulation and ICMP (v4) Too Big packet generation. After a bpf_xdp_adjust_head call, Katran code didn’t initialize the Identification field for the IPv4 header, resulting in writing content of kernel memory in that field of IP header. The issue affected all Katran versions prior to commit 6a03106ac1eab39d0303662963589ecb2374c97f
The exploitability of CVE-2023-49062 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2023-49062 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2023-49062, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2023-49062, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.187% (probability of exploit)
EPSS Percentile: 57.09%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 42.91% of others.
