CVE-2026-98589

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. When packet pointers are passed into subprograms that mutate packet data, the verifier incorrectly assumes the underlying memory remains valid across calls, failing to account for operations that invalidate or relocate...

CVE-2026-98588

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. When allocating a socket map with an excessively large entry count, a signed integer overflow occurs during cleanup when the map is released. A local user with permission to create BPF maps can trigger this issue to caus...

kernel: perf: Fix addr_filter_ranges lifetime

A flaw was found in the Linux kernel's performance events perf subsystem. This vulnerability occurs because memory allocated for event address filters is released prematurely while still in active use by other kernel processes. A local user could exploit this use-after-free flaw during performanc...

kernel: xfrm: espintcp: do not reuse an in-progress partial send

A flaw was found in the Linux kernel. The espintcp component, responsible for handling encrypted network traffic, incorrectly reuses a partial data transmission state. This can lead to an out-of-bounds read, which may allow an attacker to access sensitive information or cause other memory...

kernel: smb: client: reject a tree connect response whose byte count is too small

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote malicious SMB server could send a specially crafted tree connect response with a byte count that is too small. This incorrect handling can lead to an integer underflow, causing the client to read beyond an allocated...

CVE-2026-98583

A flaw was found in the Linux kernel's Marvell NFC Near Field Communication driver. During firmware download operations, the driver removes packet headers and reads command data before verifying that the received packet length is valid. An attacker could exploit this vulnerability by submitting a...

CVE-2026-98582

A flaw was found in the Linux kernel's ST21NFCA Near Field Communication NFC driver. The driver fails to properly validate the length of received frames when processing escape sequences. An attacker capable of sending crafted NFC frames could exploit this vulnerability to trigger an out-of-bounds...

A flaw was found in the Linux kernel's performance events perf subsystem. This vulnerability occurs because memory allocated for event address filters is released prematurely while still in active use by other kernel processes. A local user could exploit this use-after-free flaw during performanc...

This incorrect handling can lead to an integer underflow, causing the client to read beyond an allocated...

CVE-2026-98579

A flaw was found in the Linux kernel's NFC Near Field Communication subsystem. Error handling routines in the netlink interface fail to properly release allocated memory when processing service discovery requests encounters a failure. A local user can exploit this vulnerability by sending crafted...

CVE-2026-98578

A flaw was found in the Linux kernel's ST21NFCA Near Field Communication NFC driver. This vulnerability allows a Denial of Service DoS when the system encounters malformed wireless NFC responses. A nearby attacker with a crafted NFC device can transmit a truncated ISO 15693 inventory response,...

CVE-2026-98576

A flaw was found in the Linux kernel's Near Field Communication NFC subsystem. When processing certain service names and requests, the kernel attempts to log strings that lack null-termination using an unbounded format specifier. A local user can exploit this vulnerability to trigger an...

CVE-2026-98575

A flaw was found in the Linux kernel's PN533 NFC Near Field Communication driver. An attacker capable of connecting a malicious or malfunctioning USB device can supply a crafted response frame with an arbitrary data length value. Because the driver fails to validate this length against maximum...

CVE-2026-98574

A flaw was found in the Linux kernel's Broadcom GENET network driver. Improper synchronization between disabling transmission queues and stopping completion polling during interface shutdown or suspend operations can prematurely re-enable a queue. This race condition allows packet transmission to...

CVE-2026-98573

A flaw was found in the Linux kernel. An integer underflow in the networking subsystem allows an attacker to trigger an out-of-bounds memory copy by sending specially crafted Internet Protocol version 6 IPv6 packets with extension headers. This vulnerability can lead to kernel memory corruption,...

CVE-2026-98571

A flaw was found in the Linux kernel's stmmac network driver. This vulnerability can lead to a Denial of Service DoS or memory corruption when processing incoming network traffic under resource constraints. When the driver fails to allocate a network packet buffer, it recycles the underlying memo...

CVE-2026-98570

A flaw was found in the Linux kernel's IPv6 networking subsystem. An unauthenticated remote attacker can cause a Denial of Service DoS by sending network traffic through an affected IPv6 tunnel interface. Due to insufficient buffer allocation when reconstructing packet headers, an unchecked...

CVE-2026-98568

A flaw was found in the Linux kernel's VXLAN Virtual Extensible LAN networking module. A race condition can occur when link properties are modified while neighbour advertisement reply packets are being processed, leading to inconsistent buffer size calculations. A local attacker could exploit thi...

CVE-2026-98567

A flaw was found in the Linux kernel. A local privileged user could trigger a Denial of Service DoS or kernel memory corruption by causing an out-of-bounds memory write. This issue occurs in the Transmit Packet Steering XPS networking mechanism when traffic classes are decreased without clearing...
