[Pkg-samba-maint] Bug#1105747: cifs-utils: trixie kernel 6.12 and cifs-utils 7.3 do not fit together

[Matthew Ruffell]

Dear maintainer,

Yes, this is a regression in cifs-utils, and it recently has affected Ubuntu
as well.

Downstream bug:
https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/2112614

The issue is fixed in:

commit f4fd27cf60d6431d83ea18b4962aef845f9312bd
Author: Henrique Carvalho <henrique.carvalho at suse.com>
Date: Fri May 30 12:28:14 2025 -0300
Subject: cifs.upcall: correctly treat UPTARGET_UNSPECIFIED as UPTARGET_APP
Link:
https://git.samba.org/?p=cifs-utils.git;a=commit;h=f4fd27cf60d6431d83ea18b4962aef845f9312bd

which is released in 7.4 of cifs-utils yesterday.

Additionally, 7.3 also introduced a memory leak if a valid service ticket
is not
found.

Downstream bug:

This is also fixed in 7.4 of cifs-utils.

I regrettably introduced these regressions to Ubuntu when patching
CVE-2025-2312.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2099914
https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/2099917

Please package the new 7.4 release to unstable and it should fix everyone
up.

Thanks,
Matthew
