CVE-2026-63886

The CVE-2026-63886 entry concerns the Linux kernel SCSI iSCSI path, where chap_server_compute_hash() could overflow a digest buffer during BASE64 decoding. Root cause: chap_r is fed to chap_base64_decode() without validation that the decoded output fits into client_digest (kzalloc(chap->digest...

CVE-2026-63868

The CVE-2026-63868 issue affects the Linux kernel network code (net: garp) where the on-wire attribute length (ga->len) is used alongside the header to compute dlen. The subtraction dlen = sizeof(*ga) - ga->len underflows, leading to a truncated data length passed to garp_attr_lookup() and ...
