Subject: bootstd: rauc: Fix null pointer access while checking root part
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3538f788dbac291df24171ae1eeb1563ab8af53;p=thirdparty%2Fu-boot.git

bootstd: rauc: Fix null pointer access while checking root part

Fix a segmentation fault caused by a null pointer access during root
partition checking. The function part_get_info() was falsely given null
for the disk_partition struct, which later resulted in accessing a null
pointer and thus undefined behavior.

Fixes: 5d7c080ae5dc ("bootstd: rauc: Don't check root part filesystem")
