GHSA-F988-RXFV-FQH7

Vulnerability from github – Published: 2025-07-10 09:32 – Updated: 2025-11-18 15:30

Details

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.

Severity ?

7.1 (High)
