17
FAUCET Score

CVE-2022-49869 is a NULL pointer dereference vulnerability in the Linux kernel's bnxt_en network driver, affecting Linux kernel versions. This flaw can lead to a system crash during error recovery when reconfiguring coalescing settings, as datastructures may be freed prematurely. With a CVSS score of 5.5 (Medium), it requires local access and low privileges (AV:L/PR:L) to exploit, resulting in a high impact on availability (A:H) but no impact on confidentiality or integrity. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
