How to fix?

There is no fixed version for RHEL:10 kernel-rt-64k-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-devel package and not the kernel-rt-64k-devel package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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, &#34;%u&#34;, 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.
