Loading vulnerability…
CVE-2024-58077 is an uncontrolled resource-consumption issue in the Linux kernel ALSA System-on-Chip (ASoC) PCM implementation. The .prepare callback used the shared soc_pcm_ret() error handler, which broadly suppresses -EINVAL errors. That suppression was intended only for invalid userspace inputs, for which logging every error could itself permit syslog or disk-space exhaustion. Applying it to .prepare was inappropriate and could allow error conditions in that callback to be silently ignored. The upstream fix removes soc_pcm_ret() from the .prepare callback so its errors are handled without the overly broad -EINVAL suppression.

Linux kernel ASoC PCM callback handling flaw.
A Linux kernel ASoC soc-pcm error-handling issue in which the common soc_pcm_ret() function suppressed -EINVAL errors too broadly, including from the .prepare callback. The fix avoids using soc_pcm_ret() for that callback.
A Linux kernel ALSA System-on-Chip (ASoC) soc-pcm flaw involving use of soc_pcm_ret() in the .prepare callback. The error-handling behavior could create a local denial-of-service availability impact through uncontrolled resource consumption/logging-related behavior.
A Linux kernel ASoC (sound subsystem) issue in sound/soc/soc-pcm.c, where use of soc_pcm_ret() in the .prepare callback caused -EINVAL errors to be ignored more broadly than intended. The fix stops using soc_pcm_ret() for that callback so errors are handled appropriately.
