VULHUB ™

A denial of service vulnerability has been reported for the Linux kernel. Reportedly, it is possible to cause the kernel to stop responding by triggering a system call with the TF flag enabled. The vulnerability is due to the Linux kernel improperly emulating a trap call. Reportedly, the Linux kernel does not ensure that a trap will unset the TF and NT flags before entering the kernel. An attacker can exploit this vulnerability by executing a malicious application that will trigger the denial of service condition. A reboot is necessary to restore functionality. This vulnerability has been reported to affect the 2.4.19 kernels as well.
