|
|
|
A local denial of service vulnerability reportedly affects the Linux kernel. This issue arises due to a failure of the kernel to properly handle malicious, excessive file locks.
|
|
|
|
An attacker may leverage this issue to crash or hang the affected kernel and deny service to legitimate users.
|
|
|
|
It should be noted that Symantec has been unable to reproduce this issue after testing. It is possible that this vulnerability is linked to the reporter's specific configuration. More information will be added as it becomes available.
