Details

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Add error handling for old state CRTC in atomicdisable Introduce error handling to address an issue where, after a hotplug event, the cursor continues to update. This situation can lead to a kernel panic due to accessing the NULL old_state->crtc. E,g. Unable to handle kernel NULL pointer dereference at virtual address Call trace: mtkcrtcplanedisable+0x24/0x140 mtkplaneatomicupdate+0x8c/0xa8 drmatomichelpercommitplanes+0x114/0x2c8 drmatomichelpercommittailrpm+0x4c/0x158 committail+0xa0/0x168 drmatomichelpercommit+0x110/0x120 drmatomiccommit+0x8c/0xe0 drmatomichelperupdateplane+0xd4/0x128 _setplaneatomic+0xcc/0x110 drmmodecursorcommon+0x250/0x440 drmmodecursorioctl+0x44/0x70 drmioctl+0x264/0x5d8 _arm64sysioctl+0xd8/0x510 invokesyscall+0x6c/0xe0 doel0svc+0x68/0xe8 el0svc+0x34/0x60 el0t64synchandler+0x1c/0xf8 el0t64_sync+0x180/0x188 Adding NULL pointer checks to ensure stability by preventing operations on an invalid CRTC state.
