CVE-2022-50561 — iio: fix memory leak in iio_device_register_eventset()

In the Linux kernel, the following vulnerability has been resolved: iio: fix memory leak in iio_device_register_eventset() When iio_device_register_sysfs_group() returns failed, iio_device_register_eventset() needs to free attrs array. Otherwise, kmemleak would scan & report memory leak as below: unreferenced object 0xffff88810a1cc3c0 (size 32): comm "100-i2c-vcnl302", pid 728, jiffies 4295052307 (age 156.027s) backtrace: __kmalloc+0x46/0x1b0 iio_device_register_eventset at drivers/iio/industrialio-event.c:541 __iio_device_register at drivers/iio/industrialio-core.c:1959 __devm_iio_device_register at drivers/iio/industrialio-core.c:2040

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+2

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Linux Linux).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes, errors and authentication anomalies.
