Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.0.4

Description An issue in the Linux kernel causes an infinite loop and denial of service on SMP systems due to improper protection of the i size write() function. This can lead to a denial of service when exploited by a remote attacker.

Recommendations For Linux kernel versions prior to 5.0.4, update to version 5.0.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the 9p filesystem to minimize the risk of exploitation.
