CVE-2022-49512 [Medium] | Security Vulnerability in Linux Kernel

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: denali: Use managed device resources All of the resources used by this driver has managed interfaces, so use them. Otherwise we will get the following splat: [ 4.472703] denali-nand-pci 0000:00:05.0: timeout while waiting for irq 0x1000 [ 4.474071] denali-nand-pci: probe of 0000:00:05.0 failed with error -5 [ 4.473538] nand: No NAND device found [ 4.474068] BUG: unable to handle page fault for address: ffffc90005000410 [ 4.475169] #PF: supervisor write access in kernel mode [ 4.475579] #PF: error_code(0x0002) - not-present page [ 4.478362] RIP: 0010:iowrite32+0x9/0x50 [ 4.486068] Call Trace: [ 4.486269] <IRQ> [ 4.486443] denali_isr+0x15b/0x300 [denali] [ 4.486788] ? denali_direct_write+0x50/0x50 [denali] [ 4.487189] __handle_irq_event_percpu+0x161/0x3b0 [ 4.487571] handle_irq_event+0x7d/0x1b0 [ 4.487884] handle_fasteoi_irq+0x2b0/0x770 [ 4.488219] __common_interrupt+0xc8/0x1b0 [ 4.488549] common_interrupt+0x9a/0xc0
