CVE-2026-110912

In DragonFly BSD (through 6.4.2 before 4bb22ff), the ARP input handlers arpintr() and in_arpinput() in sys/netinet/if_ether.c fail to validate the ar_hln and ar_pln fields of incoming ARP packets. Consequently, in_arpreply() uses these attacker-controlled values as memcpy lengths when copying fro...

CVE-2026-110912

In DragonFly BSD through 6.4.2 before 4bb22ff, the ARP input handlers arpintr and inarpinput sys/netinet/ifether.c do not validate the hardware address length arhln and protocol address length arpln fields of incoming ARP packets. inarpreply then uses these attacker-controlled values as memcpy...

kernel: netfilter: nfnetlink_queue: do shared-unconfirmed check before segmentation

A flaw was found in the Linux kernel's netfilter nfnetlinkqueue component. This vulnerability occurs when an application does not set the FGSO capability flag and a Generic Segmentation Offload GSO packet with an unconfirmed netfilter connection nfconn entry is received. Due to an incorrect order...

kernel: USB: serial: mxuport: fix memory corruption with small endpoint

A flaw was found in the Linux kernel's USB serial mxuport driver. A malicious Universal Serial Bus USB device could exploit this vulnerability by reporting a bulk-out endpoint maximum packet size smaller than eight bytes. This can lead to user-controlled slab corruption, potentially allowing an...

kernel: bridge: mcast: Fix a possible use-after-free when removing a bridge port

A flaw was found in the Linux kernel's bridge multicast functionality. Improper management of multicast contexts when a bridge port is removed can lead to a use-after-free vulnerability. This issue could allow a local attacker to cause a system crash, resulting in a denial of service...

kernel: dmaengine: idxd: fix fdev setup failure cleanup in idxd_cdev_open()

A flaw was found in the Linux kernel's dmaengine IDXD subsystem. A race condition during file-device setup failure cleanup in the idxdcdevopen function could lead to a deadlock, causing a denial of service. Furthermore, incorrect cleanup paths could result in operations on a freed memory context,...

kernel: nfsd: don't free session slots that are still in use

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. A remote attacker could exploit a use-after-free vulnerability in the nfsd4sequence function. This occurs when the system attempts to reduce the number of active session slots while a client is still using one of the slo...

kernel: media: cx231xx: reject geometry changes while the VBI queue is busy

A flaw was found in the Linux kernel's cx231xx media driver. A local attacker can exploit this vulnerability by manipulating video and Vertical Blanking Interval VBI queue operations. This allows for a heap out-of-bounds write, which could lead to arbitrary code execution or a denial of service...

kernel: net/sched: taprio: fix use-after-free in advance_sched() on schedule switch

A flaw was found in the Linux kernel's networking scheduler, specifically within the taprio module. When the system attempts to switch schedules, a use-after-free vulnerability occurs in the advancesched function. This happens because a pointer to an old schedule entry is still used after the...

kernel: Linux kernel: Denial of Service due to use-after-free in act_tunnel_key

A flaw was found in the Linux kernel's acttunnelkey module, which manages network traffic tunneling. A race condition, where multiple operations occur in an unpredictable order, can lead to a use-after-free vulnerability. This allows a local attacker to corrupt memory, potentially causing the...

kernel: ALSA: usx2y: bound the hwdep mmap fault offset

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,...

kernel: net/sched: act_ct: Only release RCU read lock after ct_ft

A flaw was found in the Linux kernel. A race condition in the actct module, specifically during the flow table lookup, can lead to a Use-After-Free UAF vulnerability. This occurs because a critical lock is released prematurely, allowing a memory object to be freed while still in use. An attacker...

kernel: ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get

A flaw was found in the Advanced Linux Sound Architecture ALSA Sound Open Firmware SOF ipc3-control component of the Linux kernel. This vulnerability, a heap overflow, occurs due to incorrect bounds checks when handling user data lengths. An unprivileged local user can exploit this to write past...

kernel: NFSD: Prevent client use-after-free during blocked-lock reaping

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A use-after-free vulnerability can occur during the blocked-lock reaping process. This happens when a client's lock owner, without a proper reference to keep the client alive, leads to the client being prematurely freed. This...

kernel: SUNRPC: Zero rpc_gss_wire_cred at svcauth_gss_decode_credbody() entry

A flaw was found in the Linux kernel's SUNRPC Sun Remote Procedure Call component. Improper handling of credential data during the decoding process can lead to a dangling pointer, a form of memory corruption. This issue may allow a remote attacker to cause a denial of service by triggering early...
