CVE-2026-74636

A flaw was found in the Linux kernel. A race condition exists between the updateeventfields and eventdefinefields functions within the tracing subsystem. A local user, by loading specific modules, could exploit this unprotected access to kernel fields. This could lead to a kernel panic, resulting...

CVE-2026-74616

A flaw was found in the Linux kernel's XDP eXpress Data Path component. When XDP frames are cloned, a specially crafted frame can cause the skbsharedinfo structure to overwrite live packet data. This improper handling of memory during frame cloning can lead to corruption of XDP return metadata,...

CVE-2026-74705

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...

CVE-2026-74658

A flaw was found in the Linux kernel's futex subsystem. A race condition during robust futex unlock operations can occur when a process waiting on a futex is killed before it can acquire the futex, and another process subsequently re-acquires the futex through a fast path. This can lead to a...

CVE-2026-74612

A flaw was found in the Linux kernel's veth component. A remote attacker could exploit incorrect packet buffer skb length accounting after an eXpress Data Path XDP fragment adjustment. This could lead to the disclosure of sensitive kernel memory information to userspace and corruption or truncati...

CVE-2026-74609

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication protocol implementation. A race condition exists in the tipcnodelinkdown function where a link pointer is cached without proper locking. This allows another process to free the link object while the cached pointer...

CVE-2026-74611

A flaw was found in the Linux kernel's Transport Layer Security TLS 1.3 implementation. When processing TLS 1.3 records with optimistic zero-copy enabled, the tlsdecryptsg function fails to properly restore the message iterator during a retry. A remote attacker, by sending a specially crafted TLS...

CVE-2026-74692

A flaw was found in the Linux kernel's net/smc component. A time-of-check to time-of-use TOCTOU race condition allows a remote attacker to exploit a window where the listener's state is checked without proper locking. By opening TCP connections while the server is closing, an attacker can cause a...

CVE-2026-74681

A flaw was found in the Linux kernel's USB subsystem, specifically within the usbio module. An incorrect buffer size validation occurs in the usbiobulkmsg function, where the bulk IN receive buffer size is mistakenly compared against the bulk OUT endpoint size instead of the actual receive buffer...

CVE-2026-74660

A flaw was found in the Linux kernel's netfilter: ebtnflog component. This vulnerability occurs because the ebtnflog module does not properly manage references to the nfnetlinklog module. An attacker with the ability to configure ebtables rules could exploit this by causing an ebtables nflog rule...

CVE-2026-74642

A flaw was found in the ALSA USB MIDI2 EPs component of the Linux kernel. This use-after-free UAF vulnerability occurs due to a delayed release of MIDI2 endpoints, leading to an attempt to dereference an already freed Universal MIDI Packet UMP endpoint object. An attacker could potentially exploi...

CVE-2026-74635

A flaw was found in the Linux kernel's fbdev subsystem, specifically within the bitcursor function. A local user can exploit this vulnerability by writing arbitrary values to the /dev/vcsa device or by manipulating font changes. This improper handling of glyph indices can lead to an out-of-bounds...

CVE-2026-74617

A flaw was found in the Linux kernel's dibs device driver. The dibs-lock was not properly initialized when a dibs device was allocated, allowing a Global ID GID event interrupt to occur before the lock was ready. This could lead to the system attempting to acquire an uninitialized lock, potential...

CVE-2026-74610

A flaw was found in the Linux kernel's Transport Layer Security TLS implementation. An unprivileged local user could trigger a kernel null pointer dereference by sending specific data on a loopback TCP socket with the TLS Upper Layer Protocol ULP attached. This vulnerability occurs because the TL...

CVE-2026-74608

A flaw was found in the Server Message Block SMB client of the Linux kernel. A use-after-free vulnerability exists in the cifstryaddingchannels function. This occurs when a concurrent interface list refresh removes a reference to an interface while a channel creation is in progress and fails,...

CVE-2026-74604

A flaw was found in the Linux kernel's thermal/drivers/hwmon component. A use-after-free vulnerability was introduced in the thermaladdhwmonsysfs function due to the removal of a valid check in an error handling path. This flaw could allow a local attacker to cause a denial of service or...

CVE-2026-74603

A flaw was found in the Linux kernel's ptp: ocp module. This vulnerability occurs because the EEPROM board ID, a fixed-size field, is not guaranteed to be null-terminated. When this ID is processed as a C string, it may lead to an over-read beyond its intended memory boundary. This memory...

CVE-2026-74602

A flaw was found in the Linux kernel's ring-buffer component. The rballocatecpubuffer function failed to initialize the bpage-order value, leaving it as zero. This uninitialized value is later used by freebufferpage when deallocating ring-buffers with sub-buffers larger than a page size. An...

CVE-2026-74600

A flaw was found in the Linux kernel's memory management, specifically within the pagetablecheck functionality. An unprivileged local attacker could exploit this by populating a sufficient number of zero mappings. This action could lead to an overflow in the filemapcount, triggering a kernel pani...

CVE-2026-74598

A flaw was found in the Linux kernel's IPv6 networking stack. An off-by-one error in the validation of the Route Information option length RFC 4191 allows a remote attacker to craft a Router Advertisement RA packet. This crafted packet can cause the kernel to read up to 8 bytes beyond the intende...
