Astra Linux – Vulnerability in Qemu

A flaw was discovered in the vhost-vsock device of QEMU. In the event of an error, an invalid element was not detached from the virtqueue before freeing its memory, resulting in memory leakage and other unexpected issues. This issue affects QEMU versions up to 6.2.0...

kernel: Linux kernel: vsock vulnerability may lead to memory corruption

A flaw was found in the Linux kernel's vsock component. This vulnerability occurs when a connect operation on an already established socket is interrupted by a signal or timeout, causing the system to mishandle the socket's state. This incorrect handling can lead to a race condition, potentially...
