[SRU][F/J][PATCH 0/1] CVE-2024-42252

[Massimiliano Pellizzer]

[Impact]

closures: Change BUG_ON() to WARN_ON()

If a BUG_ON() can be hit in the wild, it shouldn't be a BUG_ON().

[Fix]

Oracular: Not affected
Noble:    Fixed
Jammy:    Backportred from mainline
Focal:    Applied jammy patch
Bionic:   Sent to ESM ML
Xenial:   Sent to ESM ML

[Test Case]

Compile and boot tested.

[Where problems could occur]

The fix affects the closure subsystem in the Linux kernel. An issue with
this fix may lead to improper handling of closure state transitions,
causing kernel panics during asynchronous task management. Users may
expereince failures in subsystems relying on the closure mechanism.
