CVE-2026-63995

CVE-2026-63995 affects the Linux kernel ethtool CMIS firmware update path. The CMIS FW update code reads start_cmd_payload_size from the module FW Management Features CDB reply and uses it directly as the byte count for memcpy, writing into a destination buffer of 112 bytes (ETHTOOL_CMIS_CDB_LPL_...

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-2026-63872

CVE-2026-63872 affects the Linux kernel esp path (esp4/esp6) where, on skb_to_sgvec failure during esp_output_tail, old skb page fragments are not unrefsed when a second scatterlist build fails. The root cause: a page frag reference leak in the source scatterlist if the destination sgvec creation...
