Upgrade Rocky-Linux:8 kernel-debuginfo-common-aarch64 to version 0:4.18.0-553.8.1.el8_10 or higher.
This issue was patched in RLSA-2024:4211.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debuginfo-common-aarch64 package and not the kernel-debuginfo-common-aarch64 package as distributed by Rocky-Linux.
See How to fix? for Rocky-Linux:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between async notify and socket close
The submitting thread (one which called recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete() so any code past that point risks touching already freed data.
Try to avoid the locking and extra flags altogether. Have the main thread hold an extra reference, this way we can depend solely on the atomic ref counter for synchronization.
Don't futz with reiniting the completion, either, we are now tightly controlling when completion fires.
