CVE-2026-31421

CVE-2026-31421 – Linux kernel net/sched cls_fw NULL pointer dereference . Root cause: in fw_classify(), the old-method path uses tcf_block_q() and dereferences q->handle; for shared blocks, block->q is NULL, causing a NULL pointer dereference when a nonzero skb is classified. The fix preven...

CVE-2026-31427

The CVE-2026-31427 issue in Linux kernel netfilter/nf_conntrack_sip was fixed by initializing the rtp_addr before calling nf_nat_sip SDP hooks and tracking via a have_rtp_addr flag. If SDP has no m= lines, or contains only inactive/unrecognized media, the code now avoids calling sdp_session with ...

This memory leak can enable local resource exhaustion, with the CVSS i...

CVE-2026-31558

The CVE-2026-31558 issue affects the Linux kernel LoongArch KVM component. The vulnerable code is kvm_get_vcpu_by_cpuid(), which accepts a cpuid as int; if cpuid is negative, the function could access kvm_arch::phyid_map::phys_map[] out of bounds. The documented fix makes kvm_get_vcpu_by_cpuid() ...

CVE-2026-31561

CVE-2026-31561 affects the Linux kernel: the fix removes the X86_CR4_FRED bit from the CR4 pinning mask to avoid a boot-time window where exceptions cannot be handled.

CVE-2026-31599

CVE-2026-31599 concerns a flaw in the Linux kernel vidtv driver where vidtv_pmt_stream_init can return NULL and the caller (vidtv_channel_pmt_match_sections) does not check for this, leading to a NULL pointer dereference in vidtv_psi_desc_assign and a general protection fault. The fixes add a NUL...

CVE-2026-31630

The CVE-2026-31630 issue affects the Linux kernel RXRPC procfs address formatting: AF_RXRPC procfs helpers used fixed 50-byte buffers to render local/remote socket addresses with "%pISpc", which is insufficient for the longest current IPv6-with-port forms (notably ISATAP paths). The root cause is...

CVE-2026-31644

CVE-2026-31644 affects the Linux kernel LAN966X network driver. The issue arises in lan966x_fdma_reload() when allocation of new RX buffers fails, causing the restore path to restart DMA with old descriptors whose pages were already freed, and because page_pool_put_full_page() can release pages b...

CVE-2026-31651

In CVE-2026-31651, the Linux kernel mmc: vub300 driver is affected by a NULL-deref/use-after-free on disconnect.

CVE-2026-31750 affects the Linux kernel comedi driver. The issue is a memory leak where chanlist was not freed in the exceptional exit path of do_cmd_ioctl because runflags may be unset; do_become_nonbusy() previously freed chanlist only when runflags were set. The fix adds a check in do_become_n...

CVE-2026-31773

The CVE-2026-31773 entry concerns the Linux kernel Bluetooth SMP implementation. The root cause is that the legacy responder path in smp_random() marks the STK as authenticated whenever pending_sec_level is BT_SECURITY_HIGH, which reflects the requested security level rather than the actual pairi...

CVE-2026-43010

CVE-2026-43010 : The Linux kernel fix addresses a bug where sleepable kprobe_multi programs could be attached in a non-sleepable context because bpf_kprobe_multi_link_attach() did not validate the sleepable flag.
