CVE-2026-45941
Estado: En análisisMedia (5.5)—
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.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
