Description OSIDB Bzimport 2025-02-27 03:04:19 UTC

In the Linux kernel, the following vulnerability has been resolved:

tpm: Change to kvalloc() in eventlog/acpi.c

The following failure was reported on HPE ProLiant D320:

[   10.693310][    T1] tpm_tis STM0925:00: 2.0 TPM (device-id 0x3, rev-id 0)

The above transcript shows that ACPI pointed a 16 MiB buffer for the log
events because RSI maps to the 'order' parameter of __alloc_pages_noprof().
Address the bug by moving from devm_kmalloc() to devm_add_action() and
kvmalloc() and devm_add_action().
