- Summary
- CVE-2024-41080 affecting package kernel for versions less than 6.6.64.2-9
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix possible deadlock in io_register_iowq_max_workers()
The io_register_iowq_max_workers() function calls io_put_sq_data(), which acquires the sqd->lock without releasing the uring_lock. Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lock before acquiring sqd->lock"), this can lead to a potential deadlock situation.
To resolve this issue, the uring_lock is released before calling io_put_sq_data(), and then it is re-acquired after the function call.
This change ensures that the locks are acquired in the correct order, preventing the possibility of a deadlock.
