Details

In the Linux kernel, the following vulnerability has been resolved:

ata: libata-transport: fix error handling in atatlinkadd()

In atatlinkadd(), the return value of transportadddevice() is not checked. As a result, it causes null-ptr-deref while removing the module, because transportremovedevice() is called to remove the device that was not added.

Unable to handle kernel NULL pointer dereference at virtual address 00000000000000d0 CPU: 33 PID: 13850 Comm: rmmod Kdump: loaded Tainted: G W 6.1.0-rc3+ #12 pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : devicedel+0x48/0x39c lr : devicedel+0x44/0x39c Call trace: devicedel+0x48/0x39c attributecontainerclassdevicedel+0x28/0x40 transportremoveclassdev+0x60/0x7c attributecontainerdevicetrigger+0x118/0x120 transportremovedevice+0x20/0x30 atatlinkdelete+0x88/0xb0 [libata] atatportdelete+0x2c/0x60 [libata] ataportdetach+0x148/0x1b0 [libata] atapciremoveone+0x50/0x80 [libata] ahciremove_one+0x4c/0x8c [ahci]

Fix this by checking and handling return value of transportadddevice() in atatlinkadd().
