CVE-2026-98365

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA software driver. An unauthenticated remote attacker can cause a Denial of Service DoS or out-of-bounds memory access by sending specially crafted network requests that trigger an integer overflow during memory range validatio...

CVE-2026-98175

A flaw was found in the Linux kernel's Server Message Block SMB client. This flaw allows a malicious server or network disruption to cause a Denial of Service DoS or memory corruption. The issue occurs because the client fails to cancel queued reconnection tasks before freeing connection tracking...

CVE-2026-98174

A flaw was found in the Linux kernel's SMB client subsystem. Missing list initialization and a race condition during connection reconnect operations can lead to a null-pointer dereference or list corruption. This flaw allows reconnection events, such as during network instability or server...

CVE-2026-98363

A flaw was found in the Linux kernel's ARM System Control and Power Interface SCPI driver. The driver fails to validate the upper bound of operating performance points returned by system firmware during power management configuration. A compromised or malicious firmware environment could return a...

CVE-2026-98364

A flaw was found in the Linux kernel's IPsec XFRM networking subsystem. A race condition occurs when creating policy bundles while a network device is concurrently removed, leading to a use-after-free condition where the kernel accesses already-freed device memory. A local attacker can exploit th...

K000163599: Linux kernel vulnerability CVE-2026-53375

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vce: Prevent partial address patches In the case that only one of lo/hi is valid, the patching could result in a bad address written to in FW. CVE-2026-53375 Impact There is no impact; F5...

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 race condition in QP timer handlers

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA RXE component. A race condition exists between the retransmittimer and rxedestroyqp functions. This can cause a Queue Pair QP reference count to underflow, leading to a use-after-free vulnerability. A local attacker could...

kernel: ipv6: add NULL checks for idev in SRv6 paths

A flaw was found in the Linux kernel. Missing null pointer checks in the IPv6 Segment Routing SRv6 implementation, specifically within the seg6hmacvalidateskb and ipv6srhrcv functions, can occur when an IPv6 device lacks proper configuration. This oversight may allow an attacker to trigger a null...

kernel: RDMA/rxe: Fix a use-after-free problem in rxe_mmap

A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...

kernel: ipv6: validate extension header length before copying to cmsg

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

kernel: smb: client: fix query_info() replay double-free

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the queryinfo replay mechanism attempts to free a response buffer that has already been released. This can happen if an error occurs during the initialization of an SMB2...

kernel: ipv6: exthdrs: refresh nh pointer after ipv6_hop_jumbo()

A flaw was found in the Linux kernel's handling of IPv6 extended headers. Specifically, the ipv6hopjumbo function, which processes jumbo payloads, can modify internal packet buffer skb pointers. However, the network header nh pointer is not recomputed after these modifications. This oversight cou...

kernel: RDMA/rxe: Fix OOB in free_rd_atomic_resources()

A flaw was found in the Linux kernel's RDMA/rxe component. A local user could exploit a memory corruption vulnerability in the freerdatomicresources function by updating the maxdestrdatomic value before the old array is properly freed, leading to an out-of-bounds write. This issue can cause a...

kernel: ipv6: exthdrs: refresh nh after handling HAO option

A flaw was found in the Linux kernel's IPv6 extension header processing. When processing the Home Address Option HAO, the cached network header pointer may become invalid if the packet's memory is reallocated. This can lead to incorrect parsing of subsequent IPv6 Type-Length-Value TLV options,...

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. A local, unprivileged user could exploit a race condition during a queue pair modification operation. This could lead to a use-after-free vulnerability, allowing the attacker ...

kernel: RDMA/rxe: Reject non-8-byte ATOMIC_WRITE payloads

A flaw was found in the Linux kernel's RDMA Remote Direct Memory Access subsystem, specifically within the rxe driver. A remote attacker could exploit this vulnerability by sending a specially crafted ATOMICWRITE request with a zero-byte payload. This improper handling of non-8-byte ATOMICWRITE...
