CVE-2026-53288

CVE-2026-53288 affects the Linux kernel on arm64 and concerns the early kernel mapping. The issue arises where the final part of the [data, end) segment could overflow into the next page of init_pg_end, just before early_init_stack, when using 4K pages and 2MB block entries. This creates an addit...

GHSA-89MR-XQFV-758M Gogs: UploadRepoFiles writes outside repo working tree via committed parent sym

Summary Repository.UploadRepoFiles checks for symlinks only on the leaf of the upload target osx.IsSymlinktargetPath. The siblings UpdateRepoFile, DeleteRepoFile, and GetDiffPreview use hasSymlinkInPath, which lstats every component — UploadRepoFiles is the lone outlier. An attacker with repo-wri...
