Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: seqiv – Properly handles the EBUSY error. Since seqiv only handles the special return value of EINPROGERSS, it means that in all other cases, it will free the data related to the request. However, since the caller of seqi...

CVE-2026-97924

The Linux kernel contains a vulnerability in the tracing/user_events component. The destroy_user_event() function incorrectly destroys an event's fields before attempting to remove the trace event call. If the removal fails (e.g., returning -EBUSY because the event is still enabled), the event re...
