7.0 (High) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: rcu: Fix buffer overflow in print_cpu_stall_info() The rcuc-starvation output from print_cpu_stall_info() might overflow the buffer if there is a huge difference in jiffies difference. The situation might seem improbable, but computers sometimes get very confused about time, which can result in full-sized integers, and, in this case, buffer overflow. Also, the unsigned jiffies difference is printed using %ld, which is normally for signed integers. This is intentional for debugging purposes, but it is not obvious from the code. This commit therefore changes sprintf() to snprintf() and adds a clarifying comment about intention of %ld format. Found by Linux Verification Center (linuxtesting.org) with SVACE.

The most an attacker can do is create local system conditions (heavy load, CPU starvation) that make an RCU stall warning fire.\nAC:H - Three conditions all lie outside attacker control: rcuc kthreads must exist (requires CONFIG_PREEMPT_RT or the boot parameter rcutree.use_softirq=0, non-default on mainstream kernels), an RCU CPU stall must actually be declared, and the jiffies delta must exceed ~1e8 (27.8 h at HZ=1000) or be a corrupted backwards value that the attacker cannot influence. The commit author himself describes the triggering situation as \"improbable\" and dependent on the machine being \"very confused about time.\"\nPR:L - No authentication gate protects the path itself, but reaching it requires being on the system to generate the CPU/RCU starvation load that provokes a stall warning, which an ordinary unprivileged local user can attempt. Choosing the higher of Low versus High since no capability check or root requirement guards the RCU stall detector.\nUI:N - The stall detector fires autonomously from the scheduler-clock interrupt with no victim action required. No file open, mount, or other user operation is involved.\nS:U - The overflow corrupts the kernel stack frame of print_cpu_stall_info() within the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The out-of-bounds write corrupts adjacent stack frame contents, including the ticks_title char pointer that is dereferenced by the very next pr_err(\"%s\", ...), which can dump arbitrary adjacent kernel memory to the console/dmesg. Memory corruption of this kind is leverageable for kernel information disclosure.\nI:H - This is an out-of-bounds stack write of up to 12 bytes past a 32-byte buffer, overwriting the stack canary, saved registers, and potentially the return address of print_cpu_stall_info(). Per scoring guidance an out-of-bounds write is High integrity impact regardless of how constrained the written bytes are.\nA:H - The overflow occurs in hard-IRQ context with interrupts disabled while holding the raw rnp-\u003elock spinlock; on stack-protector kernels it trips __stack_chk_fail() and panics the machine, and without it the corrupted frame yields a bad pointer dereference or corrupted return leading to an oops. Either outcome is a full kernel crash."
