Title
Input: pegasus-notetaker - fix potential out-of-bounds access
Summary
In the Linux kernel, the following vulnerability has been resolved: Input: pegasus-notetaker - fix potential out-of-bounds access In the pegasus_notetaker driver, the pegasus_probe() function allocates the URB transfer buffer using the wMaxPacketSize value from the endpoint descriptor. An attacker can use a malicious USB descriptor to force the allocation of a very small buffer. Subsequently, if the device sends an interrupt packet with a specific pattern (e.g., where the first byte is 0x80 or 0x42), the pegasus_parse_packet() function parses the packet without checking the allocated buffer size. This leads to an out-of-bounds memory access.
