CVE-2026-63978

A flaw was found in the Linux kernel's network handshake component. When a network namespace exits, pending handshake requests may not be properly released due to incorrect list handling. This can lead to resource leaks and a list-corruption race, potentially resulting in memory corruption. An...

CVE-2026-63975

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. When a device receives a connection response with an already-assigned destination Channel Identifier CID, the system may crash. This occurs because the kernel's procedure for...

CVE-2026-63971

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the sctpwaitforconnect function, where a socket lock is temporarily released and re-acquired. During this brief period, another process can move the SCTP association to a...

CVE-2026-63970

A flaw was found in the Linux kernel's vsock/virtio transport. This vulnerability occurs when the system processes zerocopy socket buffers skbs and encounters an error during memory allocation for fixed-buffer vectored data. The system may attempt to free memory incorrectly, leading to a...

CVE-2026-63967

A flaw was found in the Linux kernel's stlsm6dsx driver. This vulnerability occurs in the tagged FIFO First-In, First-Out buffer path, where a buffer on the stack is not properly initialized. A local attacker could exploit this by reading uninitialized memory from the kernel stack, leading to...

CVE-2026-63969

A flaw was found in the Linux kernel's IPv6 networking subsystem. A local attacker could trigger an infinite loop within the rt6fillnode function. This occurs when a writer removes an entry from a list without proper synchronization, causing a softirq-side process to continuously loop. The...

CVE-2026-63968

A flaw was found in the Linux kernel's IPv6 networking stack. A local attacker could trigger an infinite loop within the fib6selectpath function. This occurs when a writer removes an entry from a list without proper synchronization with readers, causing the list traversal to never terminate. This...

CVE-2026-63962

A flaw was found in the Linux kernel's USB Type-C Port Manager TCPM driver. A remote attacker, acting as a malicious USB-C port partner, could exploit an out-of-bounds write vulnerability in the svdmconsumemodes function. By sending an unsolicited 'Discover Modes ACK' with excessive data, the...

CVE-2026-63965

A flaw was found in the Linux kernel's bmp280 pressure sensor driver. The bmp580triggerhandler function fails to initialize a stack-allocated buffer, which can lead to two bytes of uninitialized stack memory being exposed to userspace. This information disclosure vulnerability could allow a local...

CVE-2026-63959

A flaw was found in the Linux kernel's USB Type-C Universal Serial Bus Type-C subsystem. A malicious or broken USB-C port can transmit a specially crafted data frame that advertises more data objects than it actually contains. This can lead to the system reading from uninitialized memory,...

CVE-2026-63961

A flaw was found in the Linux kernel's USB Type-C DisplayPort DP alternate mode. A malicious or improperly configured USB-C device can send a malformed status update Vendor Defined Object VDO, which is a data structure used for communication. This can cause the kernel to read uninitialized memory...

CVE-2026-63960

A flaw was found in the Linux kernel's USB Type-C WCOVE driver. A malicious USB device could exploit a buffer overflow vulnerability in the wcovereadrxbuffer function. This flaw allows an attacker to write data beyond the intended buffer, potentially corrupting memory on the system's interrupt...

CVE-2026-63958

A flaw was found in the Linux kernel's USB Type-C subsystem. This vulnerability allows a malicious or buggy Power Delivery Microcontroller PPM, such as embedded controller EC firmware or an I2C-attached Universal Serial Bus USB Type-C Connector System Interface UCSI controller, to provide an...

CVE-2026-63957

A flaw was found in the Linux kernel. A malicious Universal Serial Bus USB device can exploit a vulnerability in the safeserial driver by reporting a bulk-out buffer size smaller than eight bytes. This can lead to user-controlled slab corruption, a form of memory corruption, when the driver...

CVE-2026-63954

A flaw was found in the Linux kernel's High Performance File System HPFS component. This vulnerability occurs when the hpfsmapdnodebitmap function fails, leading to the system attempting to release an uninitialized buffer. An attacker could potentially trigger this condition, resulting in a syste...

CVE-2026-63956

A flaw was found in the Linux kernel's cypressm8 USB serial driver. A malicious Universal Serial Bus USB device could report a packet size smaller than eight bytes for the interrupt-out endpoint. This can lead to memory corruption, specifically user-controlled slab corruption or a NULL-pointer...

CVE-2026-63951

A flaw was found in the Linux kernel's zram module. A race condition exists in the zramwritebackendio function, which handles writeback completions. This race condition can lead to a use-after-free vulnerability, causing a system crash and resulting in a Denial of Service DoS...

CVE-2026-63953

A flaw was found in the Linux kernel's memory management component, specifically within the mm/migratedevice module. When handling device page migration, a page table pgtable allocated during the migratevmainserthugepmdpage function may not be properly freed if a specific error condition occurs...

CVE-2026-63950

A flaw was found in the Linux kernel's memory management. A local user can trigger an issue where an incorrectly initialized page counter during memory unmapping operations leads to corruption of internal memory structures. This can cause the kernel to crash, resulting in a Denial of Service DoS...

CVE-2026-63948

A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP component. A reference leak occurs in the l2capchantimeout function. When a channel's connection is null, an early exit path in the function fails to release a held channel reference. This oversigh...
