Descriptions
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/via: Avoid potential array out-of-bound in add_secret_dac_path() snd_hda_get_connections() can return a negative error code.
It may lead to accessing 'conn' array at a negative index. Found by Linux Verification Center (linuxtesting.org) with SVACE.
A vulnerability was found in the Linux kernel's ALSA subsystem in the `add_secret_dac_path()` function, where improper array handling can lead to out-of-bounds access. This occurs if the return value of the call to `snd_hda_get_connections()` returns an error code (a negative number), which is stored in the variable `nums` that is then used as the upper bound of a for loop used to access the `conn` structure. This issue could lead to undefined behavior or a memory crash due to invalid memory access.
