Description

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_subset: Fix unbalanced refcnt in geth_free geth_alloc() increments the reference count, but geth_free() fails to decrement it. This prevents the configuration of attributes via configfs after unlinking the function. Decrement the reference count in geth_free() to ensure proper cleanup.

Affected configurations

• linux linux kernel (>= 3.11 < 5.10.253) • linux linux kernel (>= 5.11 < 5.15.203) • linux linux kernel (>= 5.16 < 6.1.168) • linux linux kernel (>= 6.2 < 6.6.134) • linux linux kernel (>= 6.7 < 6.12.81) • linux linux kernel (>= 6.13 < 6.18.22) • linux linux kernel (>= 6.19 < 6.19.12) • linux linux kernel 7.0
