CVE-2024-35995

A vulnerability was found in the ACPI subsystem's CPPC driver in the Linux kernel. This issue occurs due to the mishandling of memory access bit width during performance capability calculations, which can lead to misaligned memory accesses and cause kernel panics on affected platforms...

CVE-2024-35995

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Use accesswidth over bitwidth for system memory accesses To align with ACPI 6.3+, since bitwidth can be any 8-bit value, it cannot be depended on to be always on a clean 8b boundary. This was uncovered on the Cobalt 1...

CVE-2024-35995

CVE-2024-35995 describes a Linux kernel issue where the ACPI CPPC code misread system memory by relying on bit_width, risking incorrect memory access. The fix switches to using access_width for size calculation and reads/writes using an offset and width, with a fallback to bit_width if access_wid...
