Description OSIDB Bzimport 2026-05-27 15:08:25 UTC 
In the Linux kernel, the following vulnerability has been resolved:

tpm: st33zp24: Fix missing cleanup on get_burstcount() error

get_burstcount() can return -EBUSY on timeout. When this happens,
st33zp24_send() returns directly without releasing the locality
acquired earlier.

Use goto out_err to ensure proper cleanup when get_burstcount() fails.
