CVE-2026-105164
LowCVSS 2.7Exploitation Probability (EPSS)
Low risk43th percentile - higher than 43% of all known CVEs
Summary
A flaw has been found in NASA cFS up to 7.0.1 in the function CFE_FS_ParseInputFileNameEx of the file cfe/modules/fs/fsw/src/cfe_fs_api.c. The manipulation causes an out-of-bounds read, and remote exploitation is possible. A pull request to fix this issue awaits acceptance.
Risk Assessment
An out-of-bounds read may lead to memory disclosure or system crashes. In space or critical systems, this could result in loss of control over the mission or service.
Recommendation
Monitor the status of the pull request with the fix and apply it immediately upon acceptance. Until the fix is available, restrict remote access to the file system API.
Other vulnerabilities in NASA cFS
See all- CVE-2026-67979Critical
In NASA cFS v7.0.1, the Executive Services dynamic application start path component has incorrect access control. An attacker can place a shared object on target storage, allowing arbitrary code execution.
- CVE-2026-82480High
A vulnerability was discovered in NASA cFS up to 7.0.1, affecting the CFE_SB_GetUserDataLength function in cfe_sb_util.c of the cFE Software Bus component. Manipulating TotalMsgSize/HdrSize results in integer underflow. The attack can be initiated remotely, and the vendor did not respond.
- CVE-2026-82479Medium
A vulnerability was identified in NASA cFS up to 7.0.1, affecting the OS_read function in sbn_tcp_if.c of the SBN TCP Module. Manipulating the MsgSz argument leads to buffer overflow. The attack must be carried out from within the local network. The vendor did not respond.
- CVE-2026-67978High
The SBN UDP interface in NASA cFS v7.0.1 allows an attacker to cause a Denial of Service (DoS) by sending a crafted SBN frame.
- CVE-2026-67975High
Incorrect access control in NASA cFS v7.0.1 allows attackers to arbitrarily remove low-index subscriptions and add new streams via sending TO_LAB add/remove subscription commands.
