A security update for the SUSE Linux Enterprise 16.0 and SL MIxro 6.2 kernels addresses multiple security vulnerabilities. These fixes cover a wide range of kernel subsystems including block device throttling, multipath TCP, SCSI, NVMe, networking, file systems, and others. The update resolves race conditions, use-after-free issues, memory leaks, null pointer dereferences, and other kernel bugs. The vulnerabilities have been assigned CVE identifiers ranging from CVE-2025-40147 to CVE-2025-68814. The update is intended to improve kernel stability and security by mitigating these issues.

In the Linux kernel, the following vulnerability has been resolved: tracing: fprobe events: Fix possible UAF on modules Commit ac91052f0ae5 ("tracing: tprobe-events: Fix leakage of module refcount") moved try_module_get() from __find_tracepoint_module_cb() to find_tracepoint() caller, but that introduced a possible UAF because the module can be unloaded before try_module_get(). In this case, the module object should be freed too. Thus, try_module_get() does not only fail but may access to the freed object. To avoid that, try_module_get() in __find_tracepoint_module_cb() again.
