4Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: codec: sma1307: Fix memory corruption in sma1307_setting_loaded() The sma1307->set.header_size is how many integers are in the header (there are 8 of them) but instead of allocating space of 8 integers we allocate 8 bytes. This leads to memory corruption when we copy data it on the next line: memcpy(sma1307->set.header, data, sma1307->set.header_size * sizeof(int)); Also since we're immediately copying over the memory in ->set.header, there is no need to zero it in the allocator. Use devm_kmalloc_array() to allocate the memory instead.

Technical Context
An out-of-bounds memory access occurs when code reads from or writes to memory locations outside the intended buffer boundaries. This vulnerability is classified as Out-of-bounds Write (CWE-787).
Affected Products
Affected products: Linux Linux Kernel
Remediation
A vendor patch is available — apply it immediately. Implement proper bounds checking on all array and buffer accesses. Use memory-safe languages or static analysis tools to detect OOB issues.
