CVE-2026-74524

A flaw was found in the Linux kernel. When performing memory hot-remove operations on systems using RISC-V architecture, an out-of-bounds page-table walk can occur. This issue arises because the system attempts to access memory outside of its designated boundaries, potentially leading to a kernel...

CVE-2026-74518

A flaw was found in the Linux kernel. The allocatefileregionentries function, responsible for managing huge page memory regions, can suffer from list corruption. This occurs because the listsplice operation does not properly re-initialize a list head, allowing concurrent access to shared memory...

CVE-2026-74444

A flaw was found in the Linux kernel's drm/vmwgfx driver. A local attacker could exploit an issue in the vmwcmddraw function by providing a specially crafted DRAWPRIMITIVES header with an undersized value. This can lead to an out-of-bounds read of kernel memory, potentially allowing for informati...

CVE-2026-74577

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS networking component. When processing an RTMGETROUTE request, the mplsgetroute function fails to initialize a specific byte in the response message. This oversight allows a local user to obtain a single byte of uninitialize...

CVE-2026-74575

A flaw was found in the Thunderbolt XDomain driver of the Linux kernel. A race condition can occur during the removal of a Thunderbolt cross-domain device XDomain. This allows a delayed work item to be queued after its cancellation but before the XDomain object is freed, leading to a use-after-fr...

CVE-2026-74552

A flaw was found in the Linux kernel's hwmon lm90 driver. A local user can trigger a null pointer dereference by reading sysfs attributes before the driver's registration is complete. This can lead to a system crash, resulting in a denial of service...

CVE-2026-74548

A flaw was found in the forcedeth component of the Linux kernel. The nvremove function frees the per-CPU txrxstats before unregisternetdev completes. This timing issue allows other functions, such as ndogetstats64, the NAPI/xmit data path, and nvclose/drain, to access the freed memory, leading to...

CVE-2026-74540

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol component. A use-after-free UAF vulnerability exists in the l2capleconnectrsp function, where a channel can be freed while still being referenced. This can be triggered by a remote disconnect,...

CVE-2026-74534

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. A race condition between isoconndel and isochandel functions can lead to a double-put of isoconn objects. This can result in a Use-After-Free UAF vulnerability, potentially allowing an attacker to cause a denial of service or achieve...

CVE-2026-74523

A flaw was found in the Linux kernel's qede network driver. When a qede Network Interface Card NIC with VXLAN/GENEVE tunnel ports experiences a transmit TX timeout, a deadlock can occur in the driver's recovery process. This deadlock prevents the system's networking control plane from responding,...

CVE-2026-74466

A flaw was found in the Linux kernel's s390/zcrypt component. Under specific conditions, a user-controlled domain value, derived from CCA or EP11 ioctl structures, is used as an array index without a proper speculation barrier. This oversight could allow for speculative memory reads, potentially...

CVE-2026-74463

A flaw was found in the Linux kernel's i2c: jz4780 driver. A severe deadlock can occur between the Common Clock Framework CCF and the I2C adapter lock. This happens when an I2C-controlled clock generator client is registered or modified, and a concurrent I2C transfer attempts to acquire a lock...

CVE-2026-74457

A flaw was found in the Linux kernel's peakusb module. A malicious USB device could send a specially crafted payload, leading to a heap out-of-bounds read. This vulnerability can cause a kernel panic, resulting in a Denial of Service DoS for the affected system...

CVE-2026-74449

A flaw was found in the display driver component of the Linux kernel. A local attacker could exploit a vulnerability related to how the system handles display settings, specifically when processing certain display configurations. This could lead to a system crash, resulting in a Denial of Service...

CVE-2026-74556

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...

CVE-2026-74443

A flaw was found in the Linux kernel's drm/vmwgfx component. A local attacker could exploit a vulnerability in the vmwcmddma function, where an undersized header in a Direct Memory Access DMA command body causes a pointer to underflow. This allows the attacker to overwrite authenticated fields of...

CVE-2026-74572

A flaw was found in the Linux kernel's btrfs zoned filesystem. A local user could trigger a deadlock when metadata writeback and transaction commit operations occur simultaneously. This deadlock causes the system to hang, leading to a Denial of Service DoS...

CVE-2026-74462

A flaw was found in the Linux kernel's i.MX I2C driver. During system suspend and resume, a time window exists where I2C controller resources may be disabled or not yet restored. If a workqueue triggers an I2C transfer during this period, the driver attempts to access unavailable hardware...

CVE-2026-74567

A flaw was found in the Linux kernel's key management subsystem. An unprivileged local attacker could exploit an out-of-bounds read vulnerability in the keyringgetkeychunk function. By providing specially crafted keys, the attacker can cause the system to read beyond its intended memory boundarie...
