CVE-2026-74655

CVE-2026-74655 is a Denial of Service flaw in the Linux kernel's qcom-geni UART driver (DMA-mode). The root cause is a missing flush_buffer callback in the DMA-mode uart_ops: when TCOFLUSH is issued during an in-flight TX DMA transfer, the transfer can complete after the serial core resets the tr...

In the Linux kernel, the following vulnerability has been resolved: tty: serial: qcom-geni-serial: fix slab-out-of-bounds on RX FIFO buffer Driver's probe allocates memory for RX FIFO port-rxfifo based on default RX FIFO depth, e.g. 16. Later during serial startup the qcomgeniserialportsetup...

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...
