CVE-2023-53483 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ACPI: processor: Check for null return of devm_kzalloc() in fch_misc_setup() devm_kzalloc() may fail, clk_data->name might be NULL and will cause a NULL pointer dereference later. [ rjw: Subject and changelog edits ]
A vulnerability in the Linux kernel's ACPI processor management can lead to a null pointer dereference. This issue arises in the 'fch_misc_setup()' function, where the 'devm_kzalloc()' memory allocation can fail, leaving 'clk_data->name' null. If this null value is not properly checked, it will cause a dereference error later in the execution.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for upgrading can be found in the official Linux kernel documentation.
