Fixed In Version: kernel 5.18-rc1
Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in drivers/input/input.c in the Linux Kernel, where the input_set_capability() function mishandles scenarios where an event code is outside the bitmap. This issue can lead to a kernel panic when the event code exceeds the bitmap for the specified event type, which could allow an attacker to cause a kernel crash and potential disruption of services.

Description TEJ RATHI 2024-01-12 06:14:36 UTC 
An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause a denial of service (panic) because input_set_capability mishandles the situation in which an event code falls outside of a bitmap.
