Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: perf: Fix event leak upon exit When a task is scheduled out, pending sigtrap deliveries are deferred to the target task upon resume to user space via taskwork. However, failures during the addition of an event’s callback to the...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: perf: Fixed event leakage upon execution and file release The pending task work related to perf is never waited for when a matching event occurs. In the case of a child event released directly via freeevent, this can potential...
