Lifecycle Timeline
3Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config() Fix a memory leak in gpi_peripheral_config() where the original memory pointed to by gchan->config could be lost if krealloc() fails. The issue occurs when: 1. gchan->config points to previously allocated memory 2. krealloc() fails and returns NULL 3. The function directly assigns NULL to gchan->config, losing the reference to the original memory 4. The original memory becomes unreachable and cannot be freed Fix this by using a temporary variable to hold the krealloc() result and only updating gchan->config when the allocation succeeds. Found via static analysis and code review.
Analysis
The Linux kernel's dmaengine QCOM GPI driver fails to properly handle krealloc() failures in gpi_peripheral_config(), causing memory leaks when reallocation of the channel configuration buffer fails. Local users with sufficient privileges can trigger this memory exhaustion condition, potentially leading to denial of service through resource depletion. …
