7.8 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2026-31475
High (7.8) in linux linux kernel. EPSS 0.1% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
ASoC: sma1307: fix double free of devm_kzalloc() memory
A previous change added NULL checks and cleanup for allocation
failures in sma1307_setting_loaded().
However, the cleanup for mode_set entries is wrong. Those entries are
allocated with devm_kzalloc(), so they are device-managed resources and
must not be freed with kfree(). Manually freeing them in the error path
can lead to a double free when devres later releases the same memory.
Drop the manual kfree() loop and let devres handle the cleanup.
