CVE-2021-27365: Out-of-bounds Write

An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGESIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum leng...

CVE-2021-27365

A flaw was found in the Linux kernel. A heap buffer overflow in the iSCSI subsystem is triggered by setting an iSCSI string attribute to a value larger than one page and then trying to read it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system...

CVE-2021-27363

A flaw was found in the way access to sessions and handles was handled in the iSCSI driver in the Linux kernel. A local user could use this flaw to leak iSCSI transport handle kernel address or end arbitrary iSCSI connections on the system. Mitigation The LIBISCSI module will be auto-loaded when...

Linux Kernel Buffer Overflow Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel version 5.11.3 and earlier, which stems from the fact that drivers/scsi/scsitransportiscsi.c is adversely affected by the abilit...
