CVE-2026-98353

A flaw was found in the Linux kernel's erdma Elastic Remote Direct Memory Access driver. A local user could cause a Denial of Service DoS through a system deadlock during concurrent queue creation and hardware interrupt handling. Because internal queue updates do not use interrupt-safe locking, a...

kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

kernel: linux/dim: Fix divide by 0 in RDMA DIM

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem. A divide-by-zero error can occur within the Dynamic Interrupt Moderation DIM mechanism when comparing statistics that evaluate to a zero value. A local attacker can trigger this issue during network operations to...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...

kernel: i2c: stub: Reject I2C block transfers with invalid length

A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...

kernel: ALSA: 6fire: fix use-after-free on disconnect

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

kernel: ip6_gre: Use cached t->net in ip6erspan_changelink()

A flaw was found in the Linux kernel's ip6gre module. An unprivileged user could exploit this vulnerability by migrating a network device, causing the ip6erspanchangelink function to incorrectly handle network namespace references. This error leads to a use-after-free condition when the original...

kernel: netfilter: flowtable: publish GC-visible tuple last

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

kernel: net: qrtr: restrict socket creation to the initial network namespace

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...

kernel: RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv

A flaw was found in the Linux kernel's RDMA/rxe component. The rxercv function does not adequately validate the BTH pad and ICRC fields of incoming packets before calculating the payload size. A remote attacker could exploit this by sending a specially crafted short packet or a packet with a forg...

kernel: RDMA/rxe: Fix responder UAF on IB_QP_MAX_DEST_RD_ATOMIC modify_qp

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe component.
