Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: Using rawspinlockt in ringbuf. The function bpfringbufreserve is invoked from a tracepoint, which disables preemption. Using spinlockt in this context can lead to a “sleep in atomic” warning in the RT variant. This issue is...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dropmonitor: Replace spinlock with rawspinlock. The function tracedropcommon is called with preemption disabled, and it acquires a spinlock. This is problematic for RT kernels because spinlocks are sleeping locks in this...
