CVE-2024-50302
HID: core: zero-initialize the report buffer
Qué es
In the Linux kernel, the following vulnerability has been resolved:
HID: core: zero-initialize the report buffer
Since the report buffer is used by all kinds of drivers in various ways, let's
zero-initialize it during allocation to make sure that it can't be ever used
to leak kernel memory via specially-crafted report.
CISA: The Linux kernel contains a use of uninitialized resource vulnerability that allows an attacker to leak kernel memory via a specially crafted HID report.
Qué hacer
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
