CVE-2026-97503
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.
