In the Linux kernel, the following vulnerability has been resolved: tpm: tpm tis spi: Use wait woken in wait for tmp stat wait event interruptible timeout evaluates its condition after setting the current task state to TASK INTERRUPTIBLE. With CONFIG DEBUG ATOMIC SLEEP this triggers a warning whe...

The vulnerability of the check_acpi_tpm2() function in the drivers/char/tpm/tpm_tis.c file of the Linux operating system’s alphabetic device driver module allows a attacker to cause a service failure.

The vulnerability of the checkacpitpm2 function in the drivers/char/tpm/tpmtis.c file of the Linux character device driver for TPM-based devices is related to improper memory release memory leak. Exploiting this vulnerability could allow an attacker to cause a system failure...

CVE-2022-50824 tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: tpm: tpmtis: Add the missed acpiputtable to fix memory leak In checkacpitpm2, we get the TPM2 table just to make sure the table is there, not used after the init, so the acpiputtable should be added to release the ACPI memory...

kernel: tpm_tis_spi: Account for SPI header when allocating TPM SPI xfer buffer

In the Linux kernel, the following vulnerability has been resolved: tpmtisspi: Account for SPI header when allocating TPM SPI xfer buffer The TPM SPI transfer mechanism uses MAXSPIFRAMESIZE for computing the maximum transfer length and the size of the transfer buffer. As such, it does not account...
