CVE-2026-52995

Summary (concrete details from connected docs): CVE-2026-52995 affects the Linux kernel RDS info paths (RDS/IB and RDS6/IB visitors). The root cause is that rds_for_each_conn_info() and rds_walk_conn_path_info() pass a caller-allocated on‑stack u64 buffer to visitors and then copy full item_len b...

In the Linux kernel, the following vulnerability has been resolved: fs/adfs: validate nzones in adfsvalidatebblk Reject ADFS disc records with a zero zone count during boot block validation, before the disc record is used. When nzones is 0, adfsreadmap passes it to kmallocarray0, ... which return...

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-2026-52979

CVE-2026-52979 is a Linux kernel vulnerability in the PSP subsystem. The issue arises in psp_assoc_device_get_locked(): it takes a psp_dev reference via psp_dev_get_for_sock() (which uses psp_dev_tryget() under RCU), then acquires psd->lock and drops the registration reference. If psp_dev_unre...
