Message-ID: <2024061947-CVE-2024-38577-7369@gregkh> Date: Wed, 19 Jun 2024 15:37:49 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2024-38577: rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow 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. The Linux kernel CVE team has assigned CVE-2024-38577 to this issue. Affected and fixed versions =========================== Issue introduced in 5.8 with commit edf3775f0ad6 and fixed in 6.1.93 with commit 08186d0c5fb6 Issue introduced in 5.8 with commit edf3775f0ad6 and fixed in 6.6.33 with commit 32d988f48ed2 Issue introduced in 5.8 with commit edf3775f0ad6 and fixed in 6.8.12 with commit 6593d857ce5b Issue introduced in 5.8 with commit edf3775f0ad6 and fixed in 6.9.3 with commit 1a240e138071 Issue introduced in 5.8 with commit edf3775f0ad6 and fixed in 6.10-rc1 with commit cc5645fddb0c Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2024-38577 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: kernel/rcu/tasks.h Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/08186d0c5fb64a1cc4b43e009314ee6b173ed222 https://git.kernel.org/stable/c/32d988f48ed287e676a29a15ac30701c35849aec https://git.kernel.org/stable/c/6593d857ce5b5b802fb73d8091ac9c84b92c1697 https://git.kernel.org/stable/c/1a240e138071b25944ded0f5b3e357aa99fabcb7 https://git.kernel.org/stable/c/cc5645fddb0ce28492b15520306d092730dffa48
