- Summary
- CVE-2024-43890 affecting package kernel for versions less than 5.15.167.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix overflow in getfreeelt()
"tracingmap->nextelt" in getfreeelt() is at risk of overflowing.
Once it overflows, new elements can still be inserted into the tracingmap even though the maximum number of elements (
max_elts) has been reached. Continuing to insert elements after the overflow could result in the tracingmap containing "tracingmap->maxsize" elements, leaving no empty entries. If any attempt is made to insert an element into a full tracing_map using__tracing_map_insert(), it will cause an infinite loop with preemption disabled, leading to a CPU hang problem.Fix this by preventing any further increments to "tracingmap->nextelt" once it reaches "tracingmap->maxelt".
