CVE-2025-44657
LowCVSS 3.9Exploitation Probability (EPSS)
Low risk19th percentile - higher than 19% of all known CVEs
Summary
In Linksys EA6350 V2.1.2, the chroot_local_user option is enabled in the dynamically generated vsftpd configuration file. This could lead to unauthorized access to system files, privilege escalation, or use of the compromised server as a pivot point for internal network attacks.
Risk Assessment
The organization faces the risk of router compromise, potentially allowing attackers to access sensitive data, escalate privileges, and launch attacks against other devices on the internal network.
Recommendation
It is recommended to immediately update the Linksys EA6350 firmware to the latest available version and disable the chroot_local_user option in the vsftpd configuration if possible.

- CVE-2026-7826Critical
A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.
