CVE-2026-99163

The Linux kernel contains a vulnerability in the tracing/histograms component where synthetic event fields marked as stacktraces (field->is_stack) lack proper validation if the histogram field is not a long[ stacktrace array. Due to how parse_synth_field() handles types, any 8-byte signed scal...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the tracing histograms functionality where the check synth field function fails to properly validate synthetic event fields that are stacktraces. When a histogram fiel...

CVE-2026-97936

A flaw was found in the Linux kernel's tracing subsystem. A local user with permissions to configure event triggers could cause a Denial of Service DoS or memory corruption by applying a stacktrace modifier to an unsupported field. Because the kernel fails to validate the field type, it performs ...

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...
