中文标题:
Linux kernel 安全漏洞
英文标题:
iio: accel: bmc150: Fix irq assumption regression
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bmc150加速度计中断假设错误，可能导致内核空指针取消引用。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: iio: accel: bmc150: Fix irq assumption regression The code in bmc150-accel-core.c unconditionally calls bmc150_accel_set_interrupt() in the iio_buffer_setup_ops, such as on the runtime PM resume path giving a kernel splat like this if the device has no interrupts: Unable to handle kernel NULL pointer dereference at virtual address 00000001 when read PC is at bmc150_accel_set_interrupt+0x98/0x194 LR is at __pm_runtime_resume+0x5c/0x64 (...) Call trace: bmc150_accel_set_interrupt from bmc150_accel_buffer_postenable+0x40/0x108 bmc150_accel_buffer_postenable from __iio_update_buffers+0xbe0/0xcbc __iio_update_buffers from enable_store+0x84/0xc8 enable_store from kernfs_fop_write_iter+0x154/0x1b4 This bug seems to have been in the driver since the beginning, but it only manifests recently, I do not know why. Store the IRQ number in the state struct, as this is a common pattern in other drivers, then use this to determine if we have IRQ support or not.
