3Description
In the Linux kernel, the following vulnerability has been resolved: HID: winwing: Add NULL check in winwing_init_led() devm_kasprintf() can return a NULL pointer on failure,but this returned value in winwing_init_led() is not checked. Add NULL check in winwing_init_led(), to handle kernel NULL pointer dereference error.
Analysis
In the Linux kernel, the following vulnerability has been resolved: HID: winwing: Add NULL check in winwing_init_led() devm_kasprintf() can return a NULL pointer on failure,but this returned value in. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.
Technical Context
This vulnerability is classified as NULL Pointer Dereference (CWE-476), which allows attackers to crash the application by dereferencing a null pointer. In the Linux kernel, the following vulnerability has been resolved: HID: winwing: Add NULL check in winwing_init_led() devm_kasprintf() can return a NULL pointer on failure,but this returned value in winwing_init_led() is not checked. Add NULL check in winwing_init_led(), to handle kernel NULL pointer dereference error. Affected products include: Linux Linux Kernel.
Affected Products
Linux Linux Kernel.
Remediation
A vendor patch is available. Apply the latest security update as soon as possible. Check pointers before dereferencing. Use static analysis tools to detect null pointer paths.
