NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-qemu-melange package and not the linux-qemu-melange package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

ASoC: amd: acp-mach-common: Add missing error check for clock acquisition

The acp_card_rt5682_init() and acp_card_rt5682s_init() functions did not check the return values of clk_get(). This could lead to a kernel crash when the invalid pointers are later dereferenced by clock core functions.

Fix this by:

  1. Changing clk_get() to the device-managed devm_clk_get().
  2. Adding IS_ERR() checks immediately after each clock acquisition.
