CVE-2023-52756
Description
[REJECTED CVE] A double shift vulnerability was identified in the Linux kernel's pwm subsystem. The issue involves passing a shifted value instead of a bit number to set/test_bit() functions, resulting in a double shift (e.g., BIT(BIT(1))). While this doesn't cause problems for values 0 or 1, values of 5 or higher could lead to a buffer overflow, potentially allowing attackers to cause a denial of service.
Statement
This CVE has been rejected upstream: https://lore.kernel.org/linux-cve-announce/2024060850-REJECTED-39c1@gregkh/
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
