CVE-2026-53183

CVE-2026-53183 affects the Linux kernel MPTCP implementation. The issue allows the TCP subflow receive window to shrink independently of the netns, which can inflate the MPTCP receive window and cause incoming data to exceed the receiver’s rcvbuf, potentially leading to DoS or a system becoming u...

CVE-2026-53176

CVE-2026-53176 affects the Linux kernel iSER (IB/isert) login handling in ib_isert.c. A remote iSER initiator could send a login PDU shorter than ISER_HEADERS_LEN (76), causing an integer underflow in isert_login_recv_done() when computing login_req_len, leading to a negative length used in a mem...

CVE-2026-53143

In the Linux kernel DRM/AMD KFD path, CVE-2026-53143 describes a buffer overflow during CRIU checkpoint/restore for SDMA queues on Navi3x. The v11 MQD manager used the larger v11_compute_mqd buffer (2048 bytes) for KFD_MQD_TYPE_SDMA, instead of the smaller v11_sdma_mqd (512 bytes), causing a 1536...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...
