Title
ALSA: wavefront: Fix integer overflow in sample size validation
Summary
In the Linux kernel, the following vulnerability has been resolved: ALSA: wavefront: Fix integer overflow in sample size validation The wavefront_send_sample() function has an integer overflow issue when validating sample size. The header->size field is u32 but gets cast to int for comparison with dev->freemem Fix by using unsigned comparison to avoid integer overflow.
Severity
