Linux kernel security vulnerabilities

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel that stems from the fact that when tpmreadlogefi is called multiple times, the global variable efitpmfinallogsize will at some point become negativ...

tpm2-tss: Buffer Overlow in TSS2_RC_Decode

A flaw was found in tpm2-tss, which is an open source software implementation of the Trusted Computing Group TCG Trusted Platform Module TPM 2 Software Stack TSS2. In affected versions, Tss2RCSetHandler and Tss2RCDecode index into the layerhandler with an 8-bit layer number, but the array only ha...

kernel: tpm: acpi: Call acpi_put_table() to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: tpm: acpi: Call acpiputtable to fix memory leak The start and length of the event log area are obtained from TPM2 or TCPA table, so we call acpigettable to get the ACPI information, but the acpigettable should be coupled with...

kernel: tpm: tpm_crb: Add the missed acpi_put_table() to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: tpm: tpmcrb: Add the missed acpiputtable to fix memory leak In crbacpiadd, we get the TPM2 table to retrieve information like start method, and then assign them to the priv data, so the TPM2 table is not used after the init, shou...

kernel: tpm: fix reference counting for struct tpm_chip

In the Linux kernel, the following vulnerability has been resolved: tpm: fix reference counting for struct tpmchip The following sequence of operations results in a refcount warning: 1. Open device /dev/tpmrm. 2. Remove module tpmtisspi. 3. Write a TPM command to the file descriptor opened at ste...

kernel: tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak

A memory leak flaw was found in the Linux kernel's TPM TIS driver. The checkacpitpm2 function retrieves the TPM2 ACPI table to verify its presence but fails to release the table reference via acpiputtable, resulting in a memory leak each time the function is called during driver initialization...
