Descriptions

In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse error condition.

En el archivo drivers/hid/hid-elo.c en el kernel de Linux versiones anteriores a 5.16.11, se presenta una pérdida de memoria para una determinada condición de error hid_parse

A memory leak flaw was found in elo_probe in drivers/hid/hid-elo.c in the Human Interface Devices (HID) in the Linux kernel. This issue allows an attacker to cause a denial of service when hid_parse() in elo_probe() fails.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, denial of service, double free, information leakage, memory leak, null pointer, out of bounds access, out of bounds write, privilege escalation, and use-after-free vulnerabilities.
