CVE-2026-74738 regmap: sdw-mbq: don't call an unset readable_reg callback

In the Linux kernel, the following vulnerability has been resolved: regmap: sdw-mbq: don't call an unset readablereg callback regmapsdwmbqpollbusy decides whether to poll the Function Busy bit by calling ctx-readablereg, which is a straight copy of config-readablereg. That callback is optional:...

CVE-2026-74739

CVE-2026-74739 is a slab-out-of-bounds read in the Linux kernel's net/sched cls_u32 traffic classification module. The root cause is in u32_bind_class(), which unconditionally casts a handle to tc_u_knode and dereferences &n->res; when the handle is actually a tc_u_hnode (hash table node with ...

CVE-2026-74737

CVE-2026-74737 affects the TI AM65 CPSW Network Subsystem (Nuss) driver in the Linux kernel. On the packet reception path, the helper function cppi5_desc_get_tags_ids() fills the full 16-bit Source Tag into the port_id variable, but only the lower 8-bits represent the valid MAC Port ID; the upper...

CVE-2026-74737

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: am65-cpsw-nuss: Fix portid extraction from SRC TAG On the packet reception path, the ID of the MAC Port on which the packet was received, is embedded in the RX DMA Descriptor's metadata. The ID is extracted usi...

CVE-2026-74736

CVE-2026-74736 is a Linux kernel vulnerability in the net/sched cls_bpf classifier. The function cls_bpf_prog_from_efd() retrieved a SCHED_CLS program via bpf_prog_get_type_dev() without verifying that a device-bound (offloaded) BPF program's bound netdev matched the target TC netdev. This allowe...

CVE-2026-74735 l2tp: fix tunnel and session refcount leak on seq_file release

In the Linux kernel, the following vulnerability has been resolved: l2tp: fix tunnel and session refcount leak on seqfile release In pppol2tpprocopen and l2tpdfsseqopen, iteration state pd-tunnel and pd-session is kept in seqfile private data to allow iteration across multiple read system calls...

CVE-2026-74735

CVE-2026-74735 affects the Linux kernel's L2TP (Layer 2 Tunneling Protocol) implementation. In pppol2tp_proc_open() and l2tp_dfs_seq_open(), iteration state (pd->tunnel and pd->session) is stored in seq_file private data to support multi-read() iteration. If a local user closes /proc/net/pp...

CVE-2026-74734 firewire: ohci: fix NULL pointer dereference in ar_context_release

In the Linux kernel, the following vulnerability has been resolved: firewire: ohci: fix NULL pointer dereference in arcontextrelease During the error handling path of the driver's probe function, a NULL pointer dereference can occur in arcontextrelease. When pciprobe fails early e.g., if...

CVE-2026-74734

A NULL pointer dereference in the Linux kernel's firewire/ohci driver can crash the kernel. During early probe failure (e.g., pcim_enable_device() or MMIO mapping failure), the devres cleanup calls ar_context_release(), which dereferences ctx->ohci before verifying the context was ever initial...
