  3. CVE-2026-23026
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.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: dmaengine: qcom: gpi: Corrección de fuga de memoria en gpi_peripheral_config() Corrige una fuga de memoria en gpi_peripheral_config() donde la memoria original apuntada por gchan->config podría perderse si krealloc() falla. El problema ocurre cuando: 1. gchan->config apunta a memoria previamente asignada 2. krealloc() falla y devuelve NULL 3. La función asigna directamente NULL a gchan->config, perdiendo la referencia a la memoria original 4. La memoria original se vuelve inalcanzable y no puede ser liberada Corrige esto utilizando una variable temporal para contener el resultado de krealloc() y actualizando gchan->config solo cuando la asignación tiene éxito. Encontrado mediante análisis estático y revisión de código.
