Aug 4 RESCORED — CVE-2024-38577 (Linux). CVSS 7 → 7.8 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow
There is a possibility of buffer overflow in
show_rcu_tasks_trace_gp_kthread() if counters, passed
to sprintf() are huge. Counter numbers, needed for this
are unrealistically high, but buffer overflow is still
possible.
Use snprintf() with buffer size instead of sprintf().
Found by Linux Verification Center (linuxtesting.org) with SVACE.
