Linux Distros Unpatched Vulnerability : CVE-2024-53192

medium Nessus Plugin ID 230514

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In the Linux kernel, the following vulnerability has been resolved: clk: clk-loongson2: Fix potential buffer overflow in flexible-array member access Flexible-array member `hws` in `struct clk_hw_onecell_data` is annotated with the `counted_by()` attribute. This means that when memory is allocated for this array, the _counter_, which in this case is member `num` in the flexible structure, should be set to the maximum number of elements the flexible array can contain, or fewer. In this case, the total number of elements for the flexible array is determined by variable `clks_num` when allocating heap space via `devm_kzalloc()`, as shown below: 289 struct loongson2_clk_provider *clp; ... 296 for (p = data; p->name; p++) 297 clks_num++; 298 299 clp = devm_kzalloc(dev, struct_size(clp, clk_data.hws, clks_num), 300 GFP_KERNEL); So, `clp->clk_data.num` should be set to `clks_num` or less, and not exceed `clks_num`, as is currently the case. Otherwise, if data is written into `clp->clk_data.hws[clks_num]`, the instrumentation provided by the compiler won't detect the overflow, leading to a memory corruption bug at runtime. Fix this issue by setting `clp->clk_data.num` to `clks_num`. (CVE-2024-53192)

Note that Nessus relies on the presence of the package as reported by the vendor.
