NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules-core package and not the kernel-64k-debug-modules-core package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

PM / devfreq: Fix buffer overflow in trans_stat_show

Fix buffer overflow in trans_stat_show().

Convert simple snprintf to the more secure scnprintf with size of PAGE_SIZE.

Add condition checking if we are exceeding PAGE_SIZE and exit early from loop. Also add at the end a warning that we exceeded PAGE_SIZE and that stats is disabled.

Return -EFBIG in the case where we don't have enough space to write the full transition table.

Also document in the ABI that this function can return -EFBIG error.
