kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

kernel: smb: client: validate the whole DACL before rewriting it in cifsacl

A flaw was found in the Linux kernel's Server Message Block SMB client, specifically within the cifsacl functionality. A malicious SMB server could provide a malformed Discretionary Access Control List DACL that claims to contain more Access Control Entries ACEs than are actually present. This...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

kernel: netfilter: nf_tables: release flowtable after rcu grace period on error

A flaw was found in the Linux kernel's netfilter component, specifically within the nftables subsystem. An error in releasing a flowtable after an RCU Read-Copy-Update grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and...

CVE-2026-45903

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs because several BPF helper functions lack proper memory access flags, such as MEMRDONLY or MEMWRITE. Consequently, the verifier may incorrectly assume that buffer contents remain unchanged across...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

kernel: io_uring/rsrc: reject zero-length fixed buffer import

A flaw was found in the Linux kernel's iouring subsystem. A local attacker can exploit a vulnerability in the ioimportfixed function by importing a zero-length fixed buffer. This can lead to an out-of-bounds read from slab memory, potentially resulting in information disclosure or a denial of...

kernel: Linux kernel dpaa2-switch: Kernel memory corruption via out-of-bounds write

A flaw was found in the Linux kernel dpaa2-switch driver. This out-of-bounds write vulnerability occurs because the driver does not validate the numifs value reported by the firmware against the DPSWMAXIF limit. A highly privileged attacker, capable of influencing the DPAA2 firmware or management...

kernel: Bluetooth: MGMT: validate LTK enc_size on load

A flaw was found in the Linux kernel's Bluetooth management MGMT component. An attacker could exploit a vulnerability in how Long Term Keys LTK are loaded. By providing an oversized encryption size, a stack buffer overflow can occur, potentially leading to a denial of service...

kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...

kernel: can: j1939: j1939_session_new(): fix skb reference counting

In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939sessionnew: fix skb reference counting Since j1939sessionskbqueue does an extra skbget for each new skb, do the same for the initial one in j1939sessionnew to avoid refcount underflow. mkl: clean up commit messag...

kernel: HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq

A flaw was found in the Linux kernel's Wacom Human Interface Device HID driver. This vulnerability allows a remote attacker to trigger an out-of-bounds read by sending a specially crafted, short Bluetooth HID report. This can lead to the disclosure of sensitive information from the system's memor...

kernel: netfilter: nf_tables: release flowtable after rcu grace period on error

A flaw was found in the Linux kernel's netfilter component, specifically within the nftables subsystem. An error in releasing a flowtable after an RCU Read-Copy-Update grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and...

CVE-2026-45904

A flaw was found in the Linux kernel's PowerPC Enhanced Error Handling EEH driver. This issue involves a recursive locking mechanism where the system attempts to acquire a Peripheral Component Interconnect PCI bus lock multiple times. This can lead to a system deadlock, causing unresponsiveness a...

CVE-2026-45906

A flaw was found in the Linux kernel's power supply driver for the pf1550 component. A race condition during system shutdown or startup could lead to a use-after-free vulnerability. This issue allows an interrupt to access memory that has been deallocated or not yet initialized, potentially causi...

CVE-2026-45905

A flaw was found in the Linux kernel's networking subsystem, specifically within the xfrm IPsec component. A race condition can occur during the processing of Internet Control Message Protocol ICMP error messages. This vulnerability allows a local attacker to trigger a kernel warning, which could...

CVE-2026-45908

A flaw was found in the Linux kernel's accel/amdxdna component. The amdxdnaubufmap function allocates memory for scatter-gather SG and internal SG table structures. However, it fails to free this allocated memory if subsequent operations, such as sgalloctablefrompages or dmamapsgtable, encounter ...

CVE-2026-45907

A flaw was found in the Linux kernel's mlx5e network driver. Incorrect lock ordering between devlink and netdev instance locks can lead to deadlocks.
