- Summary
- CVE-2024-41080 affecting package kernel for versions less than 5.15.176.3-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iouring: fix possible deadlock in ioregisteriowqmax_workers()
The ioregisteriowqmaxworkers() function calls ioputsqdata(), which acquires the sqd->lock without releasing the uringlock. Similar to the commit 009ad9f0c6ee ("iouring: drop ctx->uringlock before acquiring sqd->lock"), this can lead to a potential deadlock situation.
To resolve this issue, the uringlock is released before calling ioputsqdata(), 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.
