CVE-2026-80834: crypto: sun8i-ce - Remove crypto_rng interface

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 011556f71d094da61379ae3672692cae2795304e, 1017f987c5f0841f00408a78f947990c9d84b346, 19588f78db582ba4c47b4001bb27f39bb19dc432.

Low priority for now. Upgrade to Linux Linux 011556f71d094da61379ae3672692cae2795304e, 1017f987c5f0841f00408a78f947990c9d84b346, 19588f78db582ba4c47b4001bb27f39bb19dc432 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ce - Remove crypto_rng interface Since the crypto_rng interface for hardware PRNGs is unused and is redundant with hwrng and the actual Linux RNG, it's being phased out. Most drivers for it were already removed. Go ahead and remove the sun8i-ce support which is one of the only remaining ones. Note that the sun8i-ce support for hwrng remains in place. That is the interface that actually matters. As usual for crypto_rng, this driver was also buggy: its ->generate() function had a use-after-free vulnerability due to using wait_for_completion_interruptible_timeout() without handling shutting down the DMA operation if a signal is sent. There's no point in fixing this separately only to remove the code anyway, so this commit is marked with Fixes and Cc stable.
