In the Linux kernel, the following vulnerability has been resolved:
genirq/proc: Size interrupt directory names for 10-digit interrupt numbers
/proc/irq/<n>/ directory names are built in char name[10] buffers with sprintf(name, "%u", irq).
Ten-digit IRQ numbers already need 11 bytes including the trailing NUL, and current sparse-IRQ configurations allow interrupt numbers in that range.
Size the temporary name buffer for the current decimal form and switch to bounded formatting when creating or removing the proc entry.
