kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-72486

A flaw was found in the Linux kernel's mtk-adsp mailbox driver. During device teardown, if the Sound Open Firmware SOF audio driver fails to initialize, a timing issue can occur where an interrupt is processed after the associated memory has been released. This Use-After-Free UAF vulnerability ca...

CVE-2026-72483

A flaw was found in the Linux kernel's USB host driver, specifically in the max3421hubcontrol function. A malicious userspace task with access to the root hub can trigger a shift-out-of-bounds vulnerability by issuing a crafted USBDEVFSCONTROL ioctl. This can lead to arbitrary bit corruption of t...

CVE-2026-72303

A flaw was found in the ASoC Sound Open Firmware SOF ipc4-control component of the Linux kernel. This vulnerability arises from insufficient validation of the MODULENOTIFICATION payload length when handling control updates. An attacker could potentially exploit this by providing a malformed...

CVE-2026-72247

A flaw was found in the Linux kernel's netfilter nfconncount component. An incorrect comparison of conntrack zones in the connection counting logic can cause different zones to be treated as equal. This miscalculation in connection deduplication may lead to connection limits not being properly...

CVE-2026-72017

A flaw was found in the Linux kernel's MACB network driver. This driver fails to properly release outgoing Socket Kernel Buffers SKBs when the driver is closed. This continuous leakage of resources can lead to resource exhaustion over time, potentially resulting in a Denial of Service DoS conditi...

CVE-2026-72015

A flaw was found in the Linux kernel's fs/resctrl component. A double-free vulnerability occurs when a pseudo-locked group's Resource Monitoring ID RMID is freed upon creation and then again during unmount operations by the rmdirallsub function. This double-free can lead to memory corruption,...

CVE-2026-72006

A flaw was found in the Linux kernel's mlx5 driver. Repeated allocation and release of mkeys with TPH steering-tag hints can cause a memory leak of struct mlx5stidxdata. This unreferenced memory accumulates over time, potentially leading to resource exhaustion and a Denial of Service DoS for...

CVE-2026-68479

A flaw was found in the Linux kernel's Bluetooth btrtl module. This vulnerability allows a local attacker to provide a specially crafted firmware patch during Bluetooth setup. This can cause an integer underflow, leading to an oversized read and write operation. Such an operation can result in...

CVE-2026-68478

A flaw was found in the Linux kernel's Memory Stick block driver memstick: msblock. A malicious Memory Stick card, crafted to report an excessive number of blocks, can cause the driver to write beyond the bounds of an allocated memory structure. This out-of-bounds write can lead to memory...

kernel: dlm: validate length in dlm_search_rsb_tree

A flaw was found in the Linux kernel's Distributed Lock Manager dlm module. An attacker could send specially crafted network messages with an oversized length parameter to the dlmdumprsbname function. This lack of validation can lead to an out-of-bounds write in the dlmsearchrsbtree function,...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-72183

A flaw was found in the Linux kernel's Landlock security module. A sandboxed process can bypass the intended signal isolation provided by LANDLOCKSCOPESIGNAL. By manipulating file descriptors with specific fcntl calls and asynchronous I/O SIGIO delivery, a local attacker can send signals, such as...

kernel: drm/amdgpu: fix amdgpu_hmm_range_get_pages

A flaw was found in the Linux kernel, specifically within the drm/amdgpu component. This vulnerability arises from incorrect handling of a notifier sequence in the amdgpuhmmrangegetpages function, where the sequence can be read more than once. This can lead to the system processing invalid memory...

kernel: drm/amdgpu: zero-initialize GART table on allocation

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. When allocating a Graphics Address Remapping Table GART, the memory was not properly initialized. This could allow a local attacker to potentially access uninitialized memory, leading to information disclosure or unexpected system...

kernel: drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()

A flaw was found in the Linux kernel's drm/amdkfd component. An unprivileged local user can exploit an out-of-bounds write vulnerability in the kfdeventpageset function. This occurs because the function writes data without properly validating the buffer size, allowing a small buffer to trigger a...

kernel: can:bcm: arbitrary kernel code execution leading to escalate privileges

A flaw was found in the Linux kernel in net/can/bcm.c in can: bcm, where an unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation LPE. This allows the attacker to gain root privileges and take full control o...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...
