CVE-2026-72448

CVE-2026-72448 relates to the Linux kernel driver for octeontx2-pf. The vulnerability is a memory leak in the send-queue (SQ) timestamp buffer: the SQ timestamp ring is allocated with qmem_alloc() when timestamping is used, but otx2_free_sq_res() does not free sq->timestamps, causing memory to...

EUVD-2026-59309

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Validate NIX maximum LFs correctly NIX maximum number of LFs can be set via devlink command but that can be done before assigning any LFs to a PF/VF. The condition used to check whether any LFs are assigned is...

CVE-2026-72410

In the Linux kernel, the octeontx2-af component fixes an issue where the NIX maximum number of LFs could be set via devlink before any LFs were assigned to a PF/VF. The root cause was an incorrect condition used to determine if LFs were assigned; the patch corrects this check. This vulnerability ...

CVE-2026-72312

CVE-2026-72312 affects the Linux kernel component octeontx2-af and fixes an issue where VF bringup could erroneously modify the PF’s promiscuous/allmulti MCAM rules. The root cause was that mbox handling of nix_set_rx_mode (and related APIs) acted only on the PF, not the VF, potentially clearing ...

CVE-2026-72050

The CVE-2026-72050 entry concerns the Linux kernel subsystem octeontx2-af where BPID bitmap handling in setup is flawed. Specifically, nix_setup_bpids() allocates bp->bpids via rvu_alloc_bitmap() (using a plain kcalloc). If any subsequent devm_kcalloc() allocations for the BPID mapping arrays ...

CVE-2026-72045

CVE-2026-72045 : In the Linux kernel (octeontx2-af: cn10k), a VF could access another function’s LMTLINE via rvu_mbox_handler_lmtst_tbl_setup() using base_pcifunc as a direct index into the LMT map.
