CVE-2026-63888 scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix CRC overread and double-free in iscsithandletextcmd Two latent bugs in the Text-phase handler, both present since the original LIO integration in commit e48354ce078c "iscsi-target: Add iSCSI fabric suppor...

CVE-2026-63888

The CVE concerns the Linux kernel iSCSI target: two related Text-phase bugs in iscsit_handle_text_cmd() were fixed. First, a CRC32C DataDigest overread occurs because rx_size includes the CRC length when calling iscsit_crc_buf(), reading 4 bytes past the allocated text_in. The patch fixes this by...

CVE-2026-63887

The CVE-2026-63887 issue affects Linux kernel SCSI/ISCSI login handling. iscsi_encode_text_output() concatenates key=value records into login->rsp_buf using an 8192-byte buffer without checking remaining capacity, while a single PDU can carry up to 2048 pairs, potentially expanding to ~32 KiB....

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...
