CVE-2026-45871 Details
Description
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.
A vulnerability exists in the Linux kernel's TPM ST33ZP24 driver, specifically in the function responsible for sending data to the TPM. The issue arises when the 'get_burstcount()' function times out and returns an error, causing the 'st33zp24_send()' function to exit prematurely without releasing a previously acquired resource. This oversight can lead to resource leaks and potentially allow for further exploitation.
Users can apply the latest patches from the Linux kernel stable tree to address this vulnerability. The patch is included in the official Linux kernel repository.
