CVE-2025-68222: pinctrl: s32cc: fix uninitialized memory in s32_pinctrl_desc

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 3b90bd8aaeb21b513ecc4ed03299e80ece44a333, 583ac7f65791ceda38ea1a493a4859f7161dcb03, 7bbdd6c30e8fd92f7165b7730b038cfe42102004; azl3 kernel 6.6.117.1-1 on Azure Linux 3.0 6.6.119.3-1.

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.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Bug bounty scope

No known public program.

Source: bounty-targets-data (public HackerOne, Bugcrowd, Intigriti, YesWeHack listings).

Technical details

No CVSS vector for this record, so attack conditions can't be derived.

Weakness class (CWE)

Attack context

MITRE CAPEC attack patterns and ATT&CK techniques for this weakness class (CWE). A starting point for detection rules and threat hunting.

MITRE has no CAPEC/ATT&CK mapping for this CWE.
