CVE-2026-52995

The CVE-2026-52995 issue affects the Linux kernel’s RDS path: rds_for_each_conn_info() and rds_walk_conn_path_info() pass a caller-allocated on-stack buffer to visitors and then copy item_len bytes back to user space, potentially exposing uninitialized stack data. In particular, rds_ib_conn_info_...

CVE-2026-52989 nvmet-tcp: propagate nvmet_tcp_build_pdu_iovec() errors to its callers

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: propagate nvmettcpbuildpduiovec errors to its callers Currently, when nvmettcpbuildpduiovec detects an out-of-bounds PDU length or offset, it triggers nvmettcpfatalerrorcmd-queue and returns early. However, because the...

CVE-2026-52987

In the Linux kernel, CVE-2026-52987 arises from drm/amdgpu: double calls to drm_exec_fini() in userq_validate when new_addition is true. The code calls drm_exec_fini(&exec) before iterating HMM ranges and then, if amdgpu_ttm_tt_get_user_pages() fails, executes a second drm_exec_fini(&exec) on the...

CVE-2026-52956

The CVE-2026-52956 issue affects the Linux kernel’s libceph code, specifically __ceph_x_decrypt(), where a buffer region can be misinterpreted as a ceph_x_encrypt_header and hdr->magic accessed without ensuring sufficient plaintext size. This can trigger an out-of-bounds memory access when cip...
