CVE-2026-63893

A flaw was found in the Linux kernel's Thunderbolt property handling. A remote attacker, by acting as a malicious XDomain peer, could craft a special property entry that causes an integer overflow when calculating memory access. This overflow allows the system to read memory outside of the intend...

CVE-2026-63899

A flaw was found in the Linux kernel's USB serial mxuport driver. A malicious Universal Serial Bus USB device could exploit this vulnerability by reporting a bulk-out endpoint maximum packet size smaller than eight bytes. This can lead to user-controlled slab corruption, potentially allowing an...

CVE-2026-63892

A flaw was found in the Linux kernel's Thunderbolt property driver. When processing Thunderbolt properties on a non-root path, a crafted entry with a small entry-length value can lead to an out-of-bounds read. This occurs because the kmemdup function reads beyond the intended memory block and a...

CVE-2026-63890

A flaw was found in the Linux kernel's Fibre Channel over Ethernet FCoE module. An unauthenticated attacker on the same Layer 2 L2 network segment could send a specially crafted FCoE Initialization Protocol FIP frame with a malformed descriptor. This could lead to an infinite loop, causing a deni...

CVE-2026-63889

A flaw was found in the Linux kernel's Fibre Channel FC transport component. An adjacent Fibre Channel fabric actor, such as a compromised switch or fabric controller, can send a specially crafted FPIN ELS Fabric Performance Incentive Notification Extended Link Service frame. This malformed frame...

CVE-2026-63886

A flaw was found in the Linux kernel's iSCSI target functionality. This vulnerability allows a remote attacker to cause a buffer overflow by sending a specially crafted Challenge-Handshake Authentication Authentication Protocol CHAP response. The system fails to validate the length of the...

CVE-2026-63883

A flaw was found in the Linux kernel's qcomgeni serial driver. A race condition can occur when the uartflushbuffer function executes before the Direct Memory Access DMA completion interrupt is processed. This timing issue can lead to a kernel First-In, First-Out kfifo buffer underflow...

CVE-2026-63884

A flaw was found in the Linux kernel's Intel i915 graphics driver drm/i915. This use-after-free UAF vulnerability occurs during the TTM object purge operation. An attacker could potentially exploit this to cause a system crash, leading to a denial of service...

CVE-2026-63878

A flaw was found in the drm/amdgpu component of the Linux kernel. A local attacker can exploit an integer overflow vulnerability by providing an excessively large value for the numentries parameter in the GEMOP GETMAPPINGINFO ioctl. This can lead to an attempt to allocate an extremely large amoun...

CVE-2026-63876

A flaw was found in the Linux kernel's zs serial driver. During the initialization of the first serial port, a null pointer dereference occurs when a pointer derived from a null parent device pointer is accessed. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-63875

A flaw was found in the Linux kernel, specifically within the arm64 architecture's Translation Lookaside Buffer TLB management. When a Page Middle Directory PMD table was unshared, the TLB flush operation did not correctly invalidate entries in the walk cache. This oversight could leave stale PMD...

CVE-2026-63874

A flaw was found in the Linux kernel's USB Management Component Transport Protocol MCTP driver. A race condition exists between the completion of a USB Request Block URB and the cancellation of retry operations during the driver's shutdown process. This timing issue can cause a URB to be re-queue...

CVE-2026-63872

A flaw was found in the Linux kernel's implementation of the Encapsulating Security Payload ESP protocol. This vulnerability occurs in the espoutputtail function when processing network packets. If a specific operation to manage page fragments fails, the kernel does not properly release reference...

CVE-2026-63871

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. This vulnerability, a data-race, occurs because certain functions access socket-related data without proper synchronization. Specifically, isoconnectbis, isoconnectcis, isolistenbis, and isoconnbigsync can read critical fields while...

CVE-2026-63873

A flaw was found in the Linux kernel's accel/amdxdna driver. The aie2populaterange function, responsible for managing memory structures, fails to properly release a reference to a memory structure mmstruct. This oversight leads to a memory leak, which over time could result in resource exhaustion...

CVE-2026-63869

A flaw was found in the Linux kernel's mac80211 WiFi subsystem. This vulnerability allows an attacker to cause undefined behavior by injecting a specially crafted frame with an invalid radiotap header. This can lead to system instability or a denial of service DoS, potentially causing the system ...

CVE-2026-63870

A flaw was found in the Linux kernel's 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks module. When a non-IPv6 packet is transmitted over a 6LoWPAN interface, the system attempts to process uninitialized data. This can lead to system instability or a denial of service, making the syst...
