kernel: ip6: vti: Use ip6_tnl.net in vti6_changelink()
A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...
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: 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: 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: xfrm: fix stale skb->prev after async crypto steals a GSO segment
A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...
CVE-2026-98357
A flaw was found in the Linux kernel's iSCSI Extensions for Remote Direct Memory Access iSER target driver. This vulnerability can lead to arbitrary code execution or a Denial of Service DoS due to memory corruption. During connection teardown, background tasks process deferred control messages...
CVE-2026-98356
A flaw was found in the Linux kernel's Broadcom NetXtreme bnxtre driver. During device initialization, the driver fails to verify that memory allocation for the Data Center Bridging DCB workqueue succeeded. Under low-memory conditions where this setup fails, a subsequent asynchronous DCB...
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...
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: 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: 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: ip6: vti: Use ip6_tnl.net in vti6_siocdevprivate()
A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...
kernel: ip6: vti: Use ip6_tnl.net in vti6_changelink()
A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...
kernel: smb: client: fix OOB reads parsing symlink error response
A flaw was found in the Linux kernel's Server Message Block SMB client. A remote, untrusted server could send a specially crafted symlink error response, leading to an out-of-bounds read vulnerability. This could result in the disclosure of sensitive information from the kernel's memory to a loca...
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: RDMA/rxe: Reject unknown opcodes before ICRC processing
A flaw was found in the Linux kernel's Soft RoCE RDMA/rxe driver. An unauthenticated remote attacker can send a specially crafted UDP packet with an unknown opcode to trigger an out-of-bounds read. This vulnerability can lead to a kernel panic, effectively causing a Denial of Service DoS on the...
