CVE-2026-98614

The Linux kernel contains a vulnerability in the SCTP stack where the sctp_assoc_update_retran_path() function can enter an infinite loop. This occurs when all remaining transports, including the retran_path, are in the SCTP_UNCONFIRMED state, because the state check precedes the wraparound test,...

CVE-2026-98613 bpf: Bound ownership depth through local kptrs and graph roots

In the Linux kernel, the following vulnerability has been resolved: bpf: Bound ownership depth through local kptrs and graph roots Program-allocated objects can own other local objects through referenced kptrs. bpfobjfreefields follows those pointers through bpfobjdropimpl synchronously, before t...

CVE-2026-98613

The Linux kernel contains a vulnerability where program-allocated objects can own other local objects via referenced kptrs . The bpf_obj_free_fields() function follows these pointers synchronously through __bpf_obj_drop_impl() before RCU-based freeing. This allows self-referential local kptr type...

EUVD-2026-103657

In the Linux kernel, the following vulnerability has been resolved: net: usb: catc: bound the RX packet length in catcrxdone catcrxdone walks a multi-packet URB, reading a two-byte length from each packet header. Its bound, pktlen urb-actuallength, ignores the header offset and compares against t...

CVE-2026-98612 net: usb: catc: bound the RX packet length in catc_rx_done()

In the Linux kernel, the following vulnerability has been resolved: net: usb: catc: bound the RX packet length in catcrxdone catcrxdone walks a multi-packet URB, reading a two-byte length from each packet header. Its bound, pktlen urb-actuallength, ignores the header offset and compares against t...

CVE-2026-98612

The Linux kernel contains a vulnerability in the net: usb: catc component within the catc_rx_done() function. The root cause is an improper bound check where pkt_len > urb->actual_length ignores the header offset and compares against the entire transfer instead of the remaining bytes. This ...

Its bound, pktlen urb-actuallength, ignores the header offset and compares against t...

CVE-2026-98611

The Linux kernel contains a vulnerability in the bpf subsystem where the bpf_crypto_ctx_create() kfunc fails to properly validate the size of the second argument. Because the function reads params->reserved[0] and params->reserved[1] (offsets 14 and 15) before comparing params__sz against t...

CVE-2026-98611 bpf: Check params size before reading reserved fields

In the Linux kernel, the following vulnerability has been resolved: bpf: Check params size before reading reserved fields bpfcryptoctxcreate is a kfunc whose second argument is declared with the sz annotation, so the verifier only guarantees that paramssz bytes of params are valid. The function...

CVE-2026-98610 net/sched: sch_hfsc: bound the classify inner-filter walk with a drift budget

In the Linux kernel, the following vulnerability has been resolved: net/sched: schhfsc: bound the classify inner-filter walk with a drift budget hfscclassify applies the "filter may only point downwards" level check only when the filter result carries no bound class. A filter created with a flowi...

CVE-2026-98610

The Linux kernel contains a vulnerability in the net/sched: sch_hfsc component where the classify inner-filter walk is unbounded. When hfsc_adjust_levels() raises a class level without revalidating existing bindings, it can create a cycle between two interior classes. During classification, the s...
