Description Robert Frohl 2023-07-13 06:43:37 UTC

CVE-2023-21400

In multiple functions  of io_uring.c, there is a possible kernel memory
corruption due to improper locking. This could lead to local escalation of
privilege in the kernel with System execution privileges needed. User
interaction is not needed for exploitation.

reply from Android CNA:

- The fix for the CVE was included in mainline Linux and propagated down to

- For this fix, lots of patches weer cherry picked into GKI release                                                                                          branches v5.10 & v5.15

Comment 39 Gabriel Krisman Bertazi 2023-08-17 00:32:28 UTC

Also pushed fix to cve/linux-5.3 as commit ("84db304129e: io_uring: Acquire completion_lock around io_get_deferred_req (bsc#1213272 CVE-2023-21400). Sorry for the delay, I was trying to figure out why a test fails, but turns out it is unrelated to this issue.

With that, we should be done here. Reassigning back to the security team.
