The vulnerability of the triggerdatafree function in the kernel/trace/traceeventstrigger.c module, which supports kernel tracing in Linux operating systems, is related to the pointer dereferencing. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-74636

A flaw was found in the Linux kernel. A race condition exists between the updateeventfields and eventdefinefields functions within the tracing subsystem. A local user, by loading specific modules, could exploit this unprotected access to kernel fields. This could lead to a kernel panic, resulting...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: tracing/fprobe: Fixed a NULL pointer dereference in fprobefgraphentry. The fprobefgraphentry function sizes a shadow-stack reservation during one iteration of the per-ip fprobe list, and fills it during another iteration—both...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: tracing/remotes: Fixed a leak in the traceremoteallocbuffer error path. If page allocation fails in traceremoteallocbuffer, desc-nrcpus is not incremented for the current CPU. As a result, upon an error, the half-allocated rbdesc...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Tracing: It was determined that processstring also allows arrays. To address a common bug where TRACEEVENT’s TPfastassign assigns the address of an allocated string to the ring buffer and then references it in TPPrintk, which can...
