Linux kernel 安全漏洞
英文标题:
spi: tegra210-quad: Fix timeout handling
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于超时处理不当，可能导致curr_xfer字段指向陈旧内存。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: spi: tegra210-quad: Fix timeout handling When the CPU that the QSPI interrupt handler runs on (typically CPU 0) is excessively busy, it can lead to rare cases of the IRQ thread not running before the transfer timeout is reached. While handling the timeouts, any pending transfers are cleaned up and the message that they correspond to is marked as failed, which leaves the curr_xfer field pointing at stale memory. To avoid this, clear curr_xfer to NULL upon timeout and check for this condition when the IRQ thread is finally run. While at it, also make sure to clear interrupts on failure so that new interrupts can be run. A better, more involved, fix would move the interrupt clearing into a hard IRQ handler. Ideally we would also want to signal that the IRQ thread no longer needs to be run after the timeout is hit to avoid the extra check for a valid transfer.
