- Summary
- genirq/proc: Size interrupt directory names for 10-digit interrupt numbers
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
genirq/proc: Size interrupt directory names for 10-digit interrupt numbers
/proc/irq// directory names are built in
char name[10]buffers withsprintf(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.
