CVE-2026-89865

A flaw was found in the Linux kernel's qla2xxx SCSI driver. The FRU and I2C bsg handlers, responsible for data transfers, utilize a DMA Direct Memory Access buffer that is not fully cleared upon allocation. A local attacker could exploit this by manipulating the transfer length in the...

CVE-2026-89849

A flaw was found in the Linux kernel's qla2xxx SCSI driver. When the firmware delivers an unexpected status input/output control block IOCB for a non-SCSI command, the driver can incorrectly process a garbage pointer. This wild pointer dereference can lead to system instability or a denial of...

CVE-2026-89842

A flaw was found in the Linux kernel's qla2xxx SCSI driver. Under certain conditions, specifically when the firmware is not fully initialized or is in a reset state, the driver attempts to communicate with it. This can cause the system to try and process an invalid command, leading to instability...

CVE-2026-89850

A flaw was found in the Linux kernel's qla2xxx SCSI driver. This issue arises when the system attempts to check the firmware status of the qla2xxx chip while it is not operational or is recovering from an error. This can cause the system to repeatedly send a command to the hardware, which may...

CVE-2026-89854

A flaw was found in the kernel's qla2xxx SCSI driver. A use-after-free vulnerability exists due to a race condition during host teardown. When a host is being removed, the cs84xx object can be freed before its corresponding sysfs attribute is removed. A local attacker, by concurrently reading thi...

CVE-2026-89844

A flaw was found in the Linux kernel's qla2xxx SCSI driver. The qla24xxreportidacquisition function does not properly hold a lock vportslock when updating the host map btree. This oversight creates a race condition, allowing multiple concurrent updates to the host map. An attacker could exploit...
