CVE-2019-12455

Priority
Description
** DISPUTED ** An issue was discovered in sunxi_divs_clk_setup in
drivers/clk/sunxi/clk-sunxi.c in the Linux kernel through 5.1.5. There is
an unchecked kstrndup of derived_name, which might allow an attacker to
cause a denial of service (NULL pointer dereference and system crash).
NOTE: This id is disputed as not being an issue because “The memory
allocation that was not checked is part of a code that only runs at boot
time, before user processes are started. Therefore, there is no possibility
for an unprivileged user to control it, and no denial of service.”.
Notes
tyhicksThis issue has a questionable security impact. The memory allocation
is in the module init path and it isn't clear if it is actually vulnerable to
an attacker.
This issue only affects kernels built with CONFIG_CLK_SUNXI_CLOCKS
enabled. Ubuntu does not enable that config option in any kernels.
