CVE-2023-54228

Status: DeferredUnscored—

In the Linux kernel, the following vulnerability has been resolved:

regulator: raa215300: Fix resource leak in case of error

The clk_register_clkdev() allocates memory by calling vclkdev_alloc() and this memory is not freed in the error path. Similarly, resources allocated by clk_register_fixed_rate() are not freed in the error path.

Fix these issues by using devm_clk_hw_register_fixed_rate() and devm_clk_hw_register_clkdev().

After this, the static variable clk is not needed. Replace it with local variable hw in probe() and drop calling clk_unregister_fixed_rate() from raa215300_rtc_unregister_device().

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.18%
Percentile among all scored CVEs: 7
Score date: 10/6/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
