Comment 4 Petr Gajdos 2023-05-19 10:51:12 UTC 
For the POC in the upstream github issue, I get:

:/211542 # djpeg -fast 237670513-1d36b472-7dc9-4827-8694-07f0c5261bc1.jpeg 
Unsupported JPEG process: SOF type 0xc3
:/211542 #

for all TW,15sp4,15,12/libjpeg-turbo. So we might be unaffected.
Comment 9 Petr Gajdos 2023-06-02 08:25:51 UTC 
The upstream issue related to this CVE is rather:
https://github.com/libjpeg-turbo/libjpeg-turbo/issues/675

Nevertheless I get the same error:

:/211542 # djpeg -nosmooth poc_tmin124
Unsupported JPEG process: SOF type 0xc3
:/211542 #

Also the upstream issue says:
"This bug is not reproducible with the 2.1.x branch."

Patched jdlossls.c is not part of any our code stream.

Closing as invalid.
