CVE-2022-48717
In the Linux kernel, the following vulnerability has been resolved: ASoC: max9759: fix underflow in speaker_gain_control_put() Check for negative values of "priv->gain" to prevent an out of bounds access.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.22%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
