CVE-2026-98076

The Linux kernel is vulnerable to a use-after-free issue in the tracing/probes component. The root cause resides in traceprobe_define_arg_fields(), which stores pointers to probe argument name/type strings without copying them. When multiple probes share a dynamic event (kprobe, uprobe, eprobe, o...

CVE-2026-98032

The Linux kernel contains a vulnerability where concurrent subbuffer resizes can cause trace_pipe_raw readers to crash or result in uninitialized memory leaks to userspace due to the use of stale size values. The issue is addressed by modifying ring_buffer_alloc_read_page() to handle existing buf...

CVE-2026-97936

The Linux kernel contains a memory corruption vulnerability in the tracing subsystem. The event_hist_trigger() function performs an unbounded memcpy when handling the histogram stacktrace modifier, using a count directly from the event data. This allows for an out-of-bounds write that can overwri...
