ipxe

iPXE network bootloader iPXE is the leading open source network boot firmware. It provides a full PXE implementation enhanced with additional features such as: boot from a web server via HTTP or HTTPS, boot from an iSCSI, FCoE, or AoE SAN, control the boot process with a script, create interactiv...

Security update for the Linux Kernel

The SUSE Linux Enterprise 11 SP4 kernel was updated to fix various security issues: The following security issues were fixed: CVE-2026-74587: sctp: fix use-after-free of cached ASCONF chunk bsc1277821. CVE-2026-89542: SUNRPC: harden gsskrb5unwrapv2 against short tokens bsc1280387. CVE-2026-90011:...

CVE-2026-99206

A flaw was found in the Linux kernel's iSCSI target subsystem. A race condition occurs when concurrent processes update discovery authentication parameters through the configuration filesystem configfs without proper locking. A local user could exploit this vulnerability to trigger a double-free...

CVE-2026-99206

A double-free vulnerability exists in the Linux kernel within the scsi: target: iscsi component. The issue is caused by a race condition where separate configfs opens can concurrently update the discovery AuthMethod parameter. This concurrency allows both callers to free the same value within the...

kernel: scsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE

A flaw was found in the Linux kernel's iSCSI target core. This use-after-free vulnerability occurs in the corescsi3emulateproregisterandmove function. When processing iSCSI TransportIDs, a memory buffer is prematurely unmapped while still being referenced, particularly when the parameter list spa...

kernel: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show()

A flaw was found in the Linux kernel's SCSI target subsystem. This vulnerability, a buffer overflow, occurs in the tgptgpmembersshow function when processing long iSCSI IQN names. An attacker could potentially exploit this by providing a specially crafted input, leading to the disclosure of...

kernel: scsi: libiscsi_tcp: Bound SCSI Response data segment to the connection buffer

A flaw was found in the Linux kernel's libiscsitcp component. A remote attacker, acting as a malicious iSCSI target, could send a specially crafted iSCSI SCSI Command Response ISCSIOPSCSICMDRSP with an oversized data segment. This could lead to a buffer overflow in a fixed-size buffer, potentiall...
