CVE-2026-45941 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_i2c_infineon: Fix locality leak on get_burstcount() failure get_burstcount() can return -EBUSY on timeout. When this happens, the function returns directly without releasing the locality that was acquired at the beginning of tpm_tis_i2c_send(). Use goto out_err to ensure proper cleanup when get_burstcount() fails.
A vulnerability in the Linux kernel's TPM I2C Infineon driver can lead to a locality leak. The issue arises in the 'tpm_tis_i2c_send' function, where the 'get_burstcount' function may return a timeout error. When this occurs, the function exits without releasing the locality that was previously acquired. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users can upgrade to the latest version to apply the fix.
