AI-suggested
The vulnerability has been resolved by removing the crypto_rng interface and the sun8i-ss driver support entirely. Users should update to a Linux kernel version that includes this removal to mitigate the issue. No separate patch for the bugs is necessary as the code was removed. Check vendor advisories for the specific kernel versions containing this fix.
Description
A vulnerability in the Linux kernel's sun8i-ss crypto_rng interface was resolved by removing the interface entirely. The affected driver had a use-after-free flaw in its generate function and a buffer overread bug. These issues arose because the crypto_rng interface was redundant and buggy, leading to its phase-out and removal of the sun8i-ss support.
