RUSTSEC-2025-0044 Four unique double-free vulnerabilities triggered via safe APIs

The crate slice-ring-buffer was developed as a fork of slice-deque to continue maintenance and provide security patches, since the latter has been officially unmaintained RUSTSEC-2020-0158. While slice-ring-buffer has addressed some previously reported memory safety issues inherited from its fork...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Ring-Buffer: Fixed buffer locking in ringbuffersubbuforderset. Expanded the critical section in ringbuffersubbuforderset to ensure that error handling occurs with a per-buffer mutex held, thereby preventing list corruption and...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Tracing: Do not allow mmap of persistent ring buffers. When attempting to mmap a trace instance buffer that is attached to reservemem, it would cause a crash: BUG: Unable to handle a page fault for address: ffffe97bd00025c8 PF:...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Ring-Buffer: Do not trigger WARNON due to a commitoverrun. When reading a memory-mapped buffer, the reader page is simply swapped out with the last page written to the write buffer. If the reader page is the same as the commit...
