Re: [PATCH v6 08/14] LoongArch: kexec_file: Fix a modified_cmdline leak
From: sashiko-bot@kernel.org
Date: 2026-09-21 09:16:01
Also in:
driver-core, kexec, lkml, loongarch
load_other_segments() allocates modified_cmdline and stores it in
image->arch.cmdline_ptr. machine_kexec_prepare() then copies it to
KEXEC_CMDLINE_ADDR and overwrites the pointer, so the heap buffer is
leaked on every successful kexec_file_load().
Free the buffer after the copy.
