4Description
In the Linux kernel, the following vulnerability has been resolved: net: liquidio: Fix off-by-one error in PF setup_nic_devices() cleanup In setup_nic_devices(), the initialization loop jumps to the label setup_nic_dev_free on failure. The current cleanup loop while(i--) skip the failing index i, causing a memory leak. Fix this by changing the loop to iterate from the current index i down to 0. Also, decrement i in the devlink_alloc failure path to point to the last successfully allocated index. Compile tested only. Issue found using code review.
Analysis
A memory leak vulnerability exists in the Linux kernel's liquidio network driver within the setup_nic_devices() function, where an off-by-one error in the cleanup loop causes failure to deallocate the last successfully allocated device during error handling. The vulnerability affects Linux kernel versions across multiple stable branches (as evidenced by patches in 4.9, 4.14, 4.19, 5.4, 5.10, 5.15, and 5.16 stable trees per the kernel.org references). …
