Its filename was kernel-taskstatsc-parse-fix-buffer-allocation-size.patch This patch was dropped because it was withdrawn ------------------------------------------------------ From: Andrew Morton Subject: kernel/taskstats.c:parse(): fix buffer allocation size Date: Tue Jul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.
