CVE-2022-48871

A vulnerability was found in the Linux kernel's qcomgeniserial.c driver. A lack of proper size validation can lead to an out-of-bounds write caused by a mismatch between the RX FIFO buffer size and the actual RX FIFO depth after initialization. This issue can lead to memory corruption or crashes...
