------------------------------------------------------
From: Andrew Morton <akpm@linux-foundation.org>
Subject: kernel/taskstats.c:parse(): fix buffer allocation size
Date: Tue Jul 21 04:30:41 PM PDT 2026

parse() is failing to allow for the nla_strscpy()'s null termination of
the cpumask string.  This can result in the cpumask string being
truncated.

This can result in an inappropriate -EINVAL failure or in reporting for an
incorrect span of CPUs.

Fixes: f9fd8914c1ac ("[PATCH] per-task delay accounting taskstats interface: control exit data through cpumasks")
Reported-by: Oleg Deomi <oleg.deomi@gmail.com>
Closes: https://lore.kernel.org/CAByWkfZ6b1=3H9pwkz-dDQOs9cZaF-HYQ6b9Yb0=Hq2r1Vv_Pw@mail.gmail.com
