In the Linux kernel, the following vulnerability has been resolved:
perf: arm-ni: Fix missing platform_set_drvdata()
Add missing platform_set_drvdata in arm_ni_probe(), otherwise
calling platform_get_drvdata() in remove returns NULL.
A flaw was found in the Linux kernel's perf: arm-ni subsystem. This vulnerability stems from a missing call to platform_set_drvdata() during device probing, which can cause a subsequent call to platform_get_drvdata() to return a null value. A local attacker could exploit this null pointer dereference to trigger a system crash, leading to a Denial of Service (DoS). While primarily leading to a system crash, under specific conditions, this flaw could potentially be leveraged for information disclosure or arbitrary code execution.
