Summary
In the Linux kernel, the following vulnerability has been resolved: media: ts2020: fix null-ptr-deref in ts2020_probe() KASAN reported a null-ptr-deref issue when executing the following command: # echo ts2020 0x20 > /sys/bus/i2c/devices/i2c-0/new_device KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017] CPU: 53 UID: 0 PID: 970 Comm: systemd-udevd Not tainted 6.12.0-rc2+ #24 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009) RIP: 0010:ts2020_probe+0xad/0xe10 [ts2020] RSP: 0018:ffffc9000abbf598 EFLAGS: 00010202 RAX: dffffc0000000000 RBX: 0000000000000000 RCX: ffffffffc0714809 RDX: 0000000000000002 RSI: ffff88811550be00 RDI: 0000000000000010 RBP: ffff888109868800 R08: 0000000000000001 R09: fffff52001577eb6 R10: 0000000000000000 R11: ffffc9000abbff50 R12: ffffffffc0714790 R13: 1ffff92001577eb8 R14: ffffffffc07190d0 R15: 0000000000000001 FS: 00007f95f13b98c0(0000) GS:ffff888149280000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000555d2634b000 CR3: 0000000152236000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> ts2020_probe+0xad/0xe10 [ts2020] i2c_device_probe+0x421/0xb40 really_probe+0x266/0x850 ... The cause of the problem is that when using sysfs to dynamically register an i2c device, there is no platform data, but the probe process of ts2020 needs to use platform data, resulting in a null pointer being accessed. Solve this problem by adding checks to platform data.
