  2. Vulnerabilities (CVE)
  3. CVE-2025-38330
In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Fix OOB memory read access in KUnit test (ctl cache) KASAN reported out of bounds access - cs_dsp_ctl_cache_init_multiple_offsets(). The code uses mock_coeff_template.length_bytes (4 bytes) for register value allocations. But later, this length is set to 8 bytes which causes test code failures. As fix, just remove the lenght override, keeping the original value 4 for all operations.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: cs_dsp: Se corrige el acceso de lectura a memoria fuera de los límites en la prueba KUnit (caché CTL). KASAN reportó un acceso fuera de los límites: cs_dsp_ctl_cache_init_multiple_offsets(). El código usa mock_coeff_template.length_bytes (4 bytes) para la asignación de valores de registro. Sin embargo, posteriormente, esta longitud se establece en 8 bytes, lo que provoca fallos en el código de prueba. Como solución, simplemente elimine la anulación de longitud, manteniendo el valor original de 4 para todas las operaciones.
