CVE-2026-45926
In the Linux kernel, the following vulnerability has been resolved: rust: pwm: Fix potential memory leak on init error When initializing a PWM chip using pwmchip_alloc(), the allocated device owns an initial reference that must be released on all error paths. If __pinned_init() were to fail, the allocated pwm_chip would currently leak because the error path returns without calling pwmchip_put().
Affected versions
Linux kernel versions
6.19
and later are affected. Fixed in
6.19.4,
7.0
and their respective stable series.
