CVE-2026-109349
A malicious remote can send a 12-byte pack header declaring version 3 to panic the client and abort the clone or fetch.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
