Summary
In the Linux kernel, the following vulnerability has been resolved: pinctrl: s32cc: fix uninitialized memory in s32_pinctrl_desc s32_pinctrl_desc is allocated with devm_kmalloc(), but not all of its fields are initialized. Notably, num_custom_params is used in pinconf_generic_parse_dt_config(), resulting in intermittent allocation errors, such as the following splat when probing i2c-imx: WARNING: CPU: 0 PID: 176 at mm/page_alloc.c:4795 __alloc_pages_noprof+0x290/0x300 [...] Hardware name: NXP S32G3 Reference Design Board 3 (S32G-VNP-RDB3) (DT) [...] Call trace: __alloc_pages_noprof+0x290/0x300 (P) ___kmalloc_large_node+0x84/0x168 __kmalloc_large_node_noprof+0x34/0x120 __kmalloc_noprof+0x2ac/0x378 pinconf_generic_parse_dt_config+0x68/0x1a0 s32_dt_node_to_map+0x104/0x248 dt_to_map_one_config+0x154/0x1d8 pinctrl_dt_to_map+0x12c/0x280 create_pinctrl+0x6c/0x270 pinctrl_get+0xc0/0x170 devm_pinctrl_get+0x50/0xa0 pinctrl_bind_pins+0x60/0x2a0 really_probe+0x60/0x3a0 [...] __platform_driver_register+0x2c/0x40 i2c_adap_imx_init+0x28/0xff8 [i2c_imx] [...] This results in later parse failures that can cause issues in dependent drivers: s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c0-pins/i2c0-grp0: could not parse node property s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c0-pins/i2c0-grp0: could not parse node property [...] pca953x 0-0022: failed writing register: -6 i2c i2c-0: IMX I2C adapter registered s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c2-pins/i2c2-grp0: could not parse node property s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c2-pins/i2c2-grp0: could not parse node property i2c i2c-1: IMX I2C adapter registered s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c4-pins/i2c4-grp0: could not parse node property s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c4-pins/i2c4-grp0: could not parse node property i2c i2c-2: IMX I2C adapter registered Fix this by initializing s32_pinctrl_desc with devm_kzalloc() instead of devm_kmalloc() in s32_pinctrl_probe(), which sets the previously uninitialized fields to zero.
