CVE-2022-48632
In the Linux kernel, the following vulnerability has been resolved: i2c: mlxbf: prevent stack overflow in mlxbf_i2c_smbus_start_transaction() memcpy() is called in a loop while 'operation->length' upper bound is not checked and 'data_idx' also increments.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
