- Summary
- CVE-2026-98208 affecting package kernel 6.6.157.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdio_uart: fix xmit_fifo leak when the port table is full
sdio_uart_add_port() allocates the transmit fifo before claiming a slot in sdio_uart_table[]. When all UART_NR slots are taken, it returns -EBUSY with the fifo still allocated, but the probe error path only kfree()s the port, leaking the transmit fifo.
Free the fifo in the failure path of sdio_uart_add_port() itself so the function retains nothing on error.
