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...

Important: 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 Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read

A flaw was found in the Linux kernel's scsi: qla2xxx driver. A remote attacker, by sending a specially crafted Fibre Channel Protocol FCP response, could cause an integer underflow. This underflow leads to an out-of-bounds read when handling sense data, potentially disclosing sensitive memory...

kernel: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page

A flaw was found in the Linux kernel's nvmet subsystem. An unauthenticated remote attacker could exploit an out-of-bounds heap read vulnerability in the Discovery Get Log Page function. By sending a specially crafted request with a manipulated offset, an attacker could read sensitive kernel memor...

kernel: ALSA: virtio: Validate control metadata from the device

A flaw was found in the Linux kernel's ALSA virtio sound driver. A malicious or buggy virtio device can provide invalid control metadata, such as an unknown control type or an oversized value count. The driver's control handling trusts this unvalidated metadata, leading to out-of-bounds access wh...

kernel: nvmet-auth: validate reply message payload bounds against transfer length

A flaw was found in the Linux kernel's nvmet-auth component. A remote attacker, by sending a specially crafted NVMe-oF NVMe over Fabrics authentication reply message, can cause an out-of-bounds read in the kernel's memory. This vulnerability, exploitable pre-authentication, can lead to the...

kernel: blk-cgroup: fix UAF in __blkcg_rstat_flush()

A flaw was found in the Linux kernel's block input/output control group blk-cgroup component. This vulnerability, a Use-After-Free UAF, occurs when multiple block control groups are released at the same time. A race condition allows one group to remove another's entries while it is still in use,...

kernel: Linux kernel: ALSA timer use-after-free vulnerability allows privilege escalation

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A lack of serialization in the userspace-driven timer utimer TRIGGER ioctl allows two threads to concurrently call sndtimerinterrupt. This race condition can lead to a use-after-free vulnerability, wher...

kernel: vxlan: do not reuse cached ip_hdr() value after skb_tunnel_check_pmtu()

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN module. This vulnerability occurs because a cached IP header pointer is improperly reused after a Path Maximum Transmission Unit PMTU check. When the packet's head is modified during the PMTU check, the old cached IP header point...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

kernel: Bluetooth: MGMT: validate LTK enc_size on load

A flaw was found in the Linux kernel's Bluetooth management MGMT component. An attacker could exploit a vulnerability in how Long Term Keys LTK are loaded. By providing an oversized encryption size, a stack buffer overflow can occur, potentially leading to a denial of service...

kernel: ALSA: 6fire: fix use-after-free on disconnect

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

kernel: xfrm: Duplicate SPI Handling

In the Linux kernel, the following vulnerability has been resolved: xfrm: Duplicate SPI Handling The issue originates when Strongswan initiates an XFRMMSGALLOCSPI Netlink message, which triggers the kernel function xfrmallocspi. This function is expected to ensure uniqueness of the Security...

kernel: blk-mq: pop cached request if it is usable

A flaw was found in the Linux kernel's blk-mq component. This use-after-free vulnerability occurs when a task attempts to submit a bio a data structure for I/O operations to blk-mq. If the task is interrupted and sleeps after checking for a cached request but before using it, the cached request c...

kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests

A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...

kernel: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset

A flaw was found in the Linux kernel's qla2xxx SCSI driver. This vulnerability occurs when commands sent to the firmware FW are not properly cleared after a chip reset. A local attacker could exploit a race condition during direct memory access DMA unmapping, leading to a kernel panic. This can...
