CVE-2026-74557

A flaw was found in the Linux kernel's libiscsi component. An incorrect bounds check in the iscsiscsicmdrsp function allows a malicious iSCSI target to craft a SCSI Response. This can lead to a read beyond the intended buffer, causing stale connection data to be copied into the SCSI sense buffer...

CVE-2026-72087

A flaw was found in the Linux kernel's scsi: lpfc driver. The memory allocated for mboxq using mempoolalloc is not properly freed in certain early exit error paths within the lpfcsli4driverresourcesetup function. This memory leak can lead to resource exhaustion, potentially resulting in a denial ...

Moderate: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 9.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

kernel: scsi: core: Wake up the error handler when final completions race against each other

Race condition vulnerabilities were found in the Linux kernel's SCSI error handler wake-up logic. Memory ordering issues in scsidechostbusy and ordering problems in scsiehinchostfailed can cause the SCSI error handler to never wake up when command completions race against each other. This leaves...

sg3_utils: sg3_utils: arbitrary command execution via udev property injection in sg_inq --export

A flaw was found in sg3utils. The sginq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev...

CVE-2026-72086

A flaw was found in the Linux kernel's scsi: xen: scsiback component. A pvSCSI guest can trigger a resource leak by issuing specific SCSI Small Computer System Interface requests when a task management operation fails. This vulnerability allows the guest to leak command tags associated with a...

CVE-2026-72082

A flaw was found in the Linux kernel's SCSI Small Computer System Interface elx: efct module. This vulnerability occurs when an I/O abort operation fails to properly release a resource reference. This can lead to a permanent resource leak, which prevents subsequent attempts to abort the same I/O...

CVE-2026-72081

A flaw was found in the Linux kernel's scsi: elx: efct driver. When processing an unsolicited Fibre Channel Protocol FCP command that contains an unsupported additional Command Descriptor Block CDB, the system fails to properly free allocated I/O resources. This resource leak can lead to resource...

CVE-2026-72084

A flaw was found in the Linux kernel's SCSI target subsystem. An attacker, by submitting a specially crafted iSCSI TransportID during a PERSISTENT RESERVE OUT operation, could cause an out-of-bounds read. This vulnerability, which occurs due to unbounded parsing of the TransportID, can lead to a...

CVE-2026-72088

A flaw was found in the Linux kernel's hpsa SCSI driver. When a physical disk is in a reset state, the driver fails to properly unmap Direct Memory Access DMA resources. This oversight can lead to a DMA mapping leak, potentially causing resource exhaustion over time...
