CVE-2026-74665

A flaw was found in the Linux kernel. Incorrect length accounting for skb socket buffer fragments after an eXpress Data Path XDP program adjusts the fragment area can lead to an out-of-bounds read. This allows an attacker to potentially disclose sensitive kernel pointers and corrupt user-space...

CVE-2026-74662

A flaw was found in the Linux kernel's internet fragmentation inet: frags code. A race condition exists where the fragment queue timer can be activated before the queue is properly registered. This premature timer activation can lead to an inconsistent state, resulting in a stale hash node. This...

CVE-2026-74659

A flaw was found in the Linux kernel's Multiple Registration Protocol MRP bridge module. When constructing MRP test frames, the brmrpalloctestskb function fails to properly initialize certain fields. This oversight results in three uninitialized bytes being transmitted in every MRA MRPTest frame,...

CVE-2026-74655

A flaw was found in the Linux kernel. Specifically, a vulnerability exists in the qcom-geni Universal Asynchronous Receiver-Transmitter UART driver's transmit Direct Memory Access DMA buffer flush mechanism. A local user can exploit this by initiating a large write operation immediately followed ...

CVE-2026-74647

A flaw was found in the Linux kernel's fastrpc component. This race condition occurs when multiple threads concurrently attempt to unmap a buffer. If the buffer is removed from the internal list after its unmap operation has started, it can lead to an inconsistent state. A local attacker could...

CVE-2026-74645

A flaw was found in the Linux kernel's damonlrusort module. A local user with write permissions to module parameters can trigger a division-by-zero error by setting the activemembp parameter to a specific value. This manipulation causes the damosquotascore function to attempt division by zero,...

root-dirtyc0w

root-dirtyc0w CVE-2016-5195 DirtyCow Root-Privilegieneskalation Dirty COW war eine Race-Condition-Schwachstelle im Linux-Kernel. Diese Schwachstelle befand sich in den Kernel-Funktionen, die das Copy-on-Write COW Feature von Speicherzuordnungen verwalten, und ermöglichte bei Ausnutzung Prozessen...

CVE-2026-74644

A flaw was found in the Linux kernel's Data Access MONitor DAMON component. When damonpamigrate or damosvamigrate functions attempt to migrate memory pages folios to an invalid Node ID NID, these pages are not properly returned to the Least Recently Used LRU list. This improper handling results i...

CVE-2026-74641

A flaw was found in the Advanced Linux Sound Architecture ALSA usx2y driver in the Linux kernel. A local attacker, by opening the hwdep node of an attached US-X2Y device, could exploit an unbounded memory mapping mmap fault offset. This allows read-write access to arbitrary kernel memory,...

CVE-2026-74639

A flaw was found in the Linux kernel, specifically within the ALSA us144mkii driver. The captureurbcomplete function resubmits capture Urban Request Blocks URBs without properly re-anchoring them. This oversight allows URBs to remain queued on the host controller even after their associated memor...

CVE-2026-74640

A flaw was found in the Linux kernel's ALSA FireWire Control Protocol FCP. An unprivileged process can trigger an out-of-bounds write by reading controls on /dev/snd/controlC0 after an oversized Level Meter map has been installed. This occurs because the fcpmeterctlget function writes beyond its...

CVE-2026-74634

A flaw was found in the Linux kernel's ring-buffer component. This vulnerability occurs when the system attempts to change the order of sub-buffers while resizing is disabled, leading to memory being freed prematurely. A local attacker could exploit this use-after-free condition to potentially...

CVE-2026-74628

A flaw was found in the Linux kernel's x25 network protocol. The way timers are managed for x25 sockets can lead to a use-after-free vulnerability. Specifically, a timer might be rearmed after the associated socket has been deallocated, causing the system to access freed memory. This could...

CVE-2026-74627

A flaw was found in the Linux kernel's net: devmem component. This vulnerability occurs when netiov and page-backed fragments are improperly mixed within a single skb socket buffer in the zerocopyfillskbfromdevmem function. This improper handling can lead to a system crash, resulting in a Denial ...

CVE-2026-74623

A flaw was found in the Linux kernel's atlantic network driver. When a network interface using this driver is deinitialized while under transmit TX or XDPTX load, certain transmit buffers are not properly released. This oversight leads to a memory leak, which can prevent the proper shutdown of...

CVE-2026-74620

A flaw was found in the Linux kernel's net/sched subsystem, specifically within the actgact and actpolice modules. A local user could exploit this vulnerability by providing a specially crafted control action that bypasses proper range checks. This improper handling of control actions leads to an...

CVE-2026-74630

A flaw was found in the Linux kernel's IPv6 subsystem. The in6devget function can incorrectly increment the reference count of an inet6dev object after it has been freed, leading to a use-after-free vulnerability. A local attacker could exploit this to cause memory corruption, potentially resulti...

kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O

A flaw was found in the Kernel-based Virtual Machine KVM for x86. This vulnerability occurs when KVM incorrectly re-checks Level 1 L1 intercepts during the completion of userspace I/O emulation for a Level 2 L2 instruction. If the L1 or host userspace modifies I/O interception settings during thi...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...
