CVE-2023-53710

CVE-2023-53710 affects the Linux kernel, specifically the mt7921 wireless driver (mt76/mt7921). The issue is a NULL pointer dereference triggered during ACPI SAR table handling, where an incorrect return code prevented marking the SAR table as invalid. Evidence in multiple sources shows the crash...

CVE-2022-50562

CVE-2022-50562 : In the Linux kernel, the TPM ACPI path leaked memory because acpi_get_table() was not paired with acpi_put_table(). The fix adds acpi_put_table() to release ACPI memory and also removes a redundant empty line in tpm_read_log_acpi(). This resolves a memory leak in the TPM2/TCPA ev...
