tftp: tftp-hpa: Denial of Service due to out-of-bounds read/write in remap engine

A flaw was found in tftp-hpa. When the in.tftpd remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the genmatchstring function. This leads to out-of-bounds read/write operations. A remote, unauthenticated...

undici: undici: Denial of Service via unrequested WebSocket subprotocol

A flaw was found in undici. A remote attacker can exploit this vulnerability by responding with an unrequested WebSocket subprotocol during the opening handshake. This causes the undici WebSocket client to crash the entire Node.js process, leading to a denial of service DoS...

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: smb: client: fix double-free in SMB2_flush() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error within the SMB2flush replay mechanism, occurs when the system attempts to free a memory buffer twice. A malicious SMB server could exploit this by sending a specially crafted flush...

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: fix use-after-free in ip6_finish_output2()

A flaw was found in the Linux kernel's IPv6 networking stack. A use-after-free vulnerability exists in the ip6finishoutput2 function, where a cached pointer to the IPv6 destination address can become stale after memory reallocation. An attacker could potentially exploit this to leak sensitive...

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...

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: 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.
