Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to up to 5.0.2 (Operating System). This affects the function i_size_write of the component p9 Filesystem. The manipulation as part of a Infinite Loop leads to a infinite loop vulnerability. CWE is classifying the issue as CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. This is going to have an impact on availability. The summary by CVE is:

An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems.

The weakness was presented 09/19/2019. This vulnerability is uniquely identified as CVE-2019-16413 since 09/18/2019. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1499 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 247074 (Linux Distros Unpatched Vulnerability : CVE-2019-16413), which helps to determine the existence of the flaw in a target environment.

Upgrading to version bis 5.0.3 eliminates this vulnerability.
