Comment 1 Takashi Iwai 2022-04-04 15:36:57 UTC

The ax25 stuff is enabled on SLE15-SP3 and SLE15-SP4 but shipped only with kernel-*-optional for Leap.

Comment 2 Gabriele Sonnu 2022-04-04 15:56:30 UTC

Tracking as affected:

- SLE15-SP3 
- SLE15-SP4

Comment 3 Takashi Iwai 2022-04-04 16:07:05 UTC

Waiting for CVSS to judge whether to backport to SLE15-SP4-GA or not.

Comment 4 Takashi Iwai 2022-04-05 06:37:18 UTC

The fixes pushed to both SLE15-SP3 and SLE15-SP4 branches.
