  "title": "irqchip/renesas-rzg2l: Fix loss of interrupt",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  irqchip/renesas-rzg2l: Fix loss of interrupt  rzg2l_clear_irq_int() and rzg2l_clear_tint_int() perform a read-modify-write on the ISCR/TSCR status registers to clear the bit for the interrupt just handled. Since these registers are write-0-to-clear per bit, this is racy:  If another interrupt\u0027s status bit gets set between the read and the write, that bit is written back as 0 by the software-constructed value, clearing an interrupt that hasn\u0027t been serviced yet and losing it.  This can be reproduced by triggering multiple interrupts at once, e.g.:    gpioset -c gpiochip0 355=0 353=0 328=0 352=0  Fix this by writing back only the bit being cleared, with all other bits set to 1, instead of read-modify-writing the whole register.  Since 1-bits are left unchanged by hardware, concurrently-set status bits for other interrupts are preserved.",
