Hi! You recently fixed a bug related to improper validation of "junk" data. However, the original reporter missed a crucial detail: the bug allowed for an out-of-bounds (OOB) access in the kernel slab, which—with certain manipulations—could lead to privilege escalation. I would like to ask for your permission to file a CVE for your product or GIT security.
