CVE-2026-63945

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. A race condition exists where the isosockcleartimer function can access connection data without proper locking, while another function, isoconndel, concurrently modifies the same data. This can lead to a NULL point...

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8575-1: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8574-1 linux-gcp-fips vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

USN-8574-1: Linux kernel (GCP FIPS) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

CVE-2026-64074

A flaw was found in the Linux kernel. This vulnerability, located in the statmountmntidmap function, involves an out-of-bounds write. When processing mount ID mappings, an internal buffer can be incorrectly accessed due to an unchecked overflow, leading to a single-byte overwrite. This memory...

CVE-2026-64138

A flaw was found in the ksmbd module of the Linux kernel. This vulnerability arises from improper validation of Security Identifiers SIDs within the NT Security Descriptor smbntsd during Access Control List ACL inheritance. An attacker could exploit this to bypass intended security restrictions,...

CVE-2026-64146

A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System component. During the initialization of inode extended attributes xattrs, certain error conditions can lead to a leak of metadata buffers. This memory leak can result in a denial of service DoS due to resource exhaustion...

CVE-2026-64117

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This use-after-free vulnerability arises from incorrect handling of fast-RX rate data during mesh processing. This can lead to memory corruption, which an attacker could potentially exploit to cause a system crash denial of service...

CVE-2026-64076

A flaw was found in the Linux kernel's Netfilter ebtables module. A race condition during the module's initialization allows sockopts to be exposed globally before they are fully registered. This could potentially lead to unexpected behavior or security vulnerabilities if exploited by a local...

CVE-2026-64059

A flaw was found in the Linux kernel's network filesystem netfs component. The netfsperformwrite function, responsible for handling write operations, does not correctly manage private data associated with memory pages, known as folios. This improper handling can lead to memory leaks, where system...

kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp

A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP implementation. A remote Bluetooth Low Energy BLE device can exploit this by sending a specially crafted L2CAP ECRED reconfiguration response. This can lead to the corruption of the channel list,...

CVE-2026-64064

A flaw was found in the Linux kernel's netfs component. When a streaming write operation is performed, a memory page folio can remain marked as 'dirty' even after the associated data is removed by a file truncation. If this dirty page is subsequently accessed through a memory-mapped file mmap, th...

CVE-2026-64066

A flaw was found in the Linux kernel's netfs component. The netfsreadtopagecache function does not properly pause the generation of new subrequests when a previously issued subrequest has failed. This oversight can lead to continued resource consumption or incorrect system state, potentially...

CVE-2026-64040

A flaw was found in the Linux kernel's cachefiles subsystem. When the vfsmkdir function fails, the system does not correctly extract the error code from the returned error pointer. This improper handling can lead to a null pointer being returned instead of a valid error, potentially causing a...

CVE-2026-64110

A flaw was found in the Linux kernel's igc driver, which handles Intel Gigabit Ethernet devices. When the igcfpeinittxdescriptor function fails to initialize a transmit descriptor, an allocated socket buffer skb is not properly released. This oversight leads to a memory leak within the kernel. Ov...

kernel: RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()

A flaw was found in the Linux kernel's RDMA/mana component. A local user could trigger a kernel corruption by providing specific configurations through the user Application Programming Interface uAPI that cause an internal error. This issue arises when Work Queues WQs are specified to share the...

CVE-2026-64039

A flaw was found in the Linux kernel's display snapshotting component. The system's snapshotting code incorrectly handles memory alignment for display data, leading to a significant memory overallocation. This vulnerability could allow a local attacker to cause a denial of service DoS by consumin...

CVE-2026-64079

A flaw was found in the Linux kernel's netfilter xtables component. A race condition occurs when a network namespace netns table is registered, making it visible with a null operations ops pointer. If a pernet exit operation runs concurrently, it can attempt to unregister the table using this nul...

CVE-2026-64143

A flaw was found in the Linux kernel's Uniwill laptop driver. This vulnerability allows a local user to potentially cause permanent damage to the battery on certain older Uniwill laptop models. The issue arises when the battery charging limit feature is enabled through a 'force' module parameter,...
