CVE-2026-98622 net/sched: act_ct: don't WARN on benign flow_offload_alloc() failure

In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: don't WARN on benign flowoffloadalloc failure flowoffloadalloc returns NULL when the conntrack entry is dying e.g. raced with a conntrack flush or when the GFPATOMIC allocation fails; both are expected under loa...

CVE-2026-98622

The Linux kernel contains a flaw in the net/sched: act_ct component where the flow_offload_alloc() function triggers a kernel warning upon failure. These failures occur during benign scenarios, such as when a conntrack entry is dying (e.g., during a raced conntrack flush) or when GFP_ATOMIC alloc...

CVE-2026-98621 net: gue: reject invalid REMCSUM offsets

In the Linux kernel, the following vulnerability has been resolved: net: gue: reject invalid REMCSUM offsets The REMCSUM option carries an absolute checksum start and checksum field offset. gueremcsum passes them to skbremcsumprocess, whose partial path stores offset - start in the u16...

CVE-2026-98621

The Linux kernel contains a vulnerability where the REMCSUM option can cause an integer underflow . The gue_remcsum() function passes an absolute checksum start and field offset to skb_remcsum_process(), which calculates the difference and stores it in a u16 variable. If the offset is less than t...

CVE-2026-98620

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkethsoc: unregister netdevices in case of probe failure If registernetdev fails for one of the MTKMAXDEVS devices in mtkprobe, the error path jumps to errdeinitppe, skipping mtkunregdev. The previously registered...

CVE-2026-98619

In the Linux kernel, the following vulnerability has been resolved: net: ethtool: keep rtnllock for the ioctl self test An offline self test that brings the interface down and back up with netifclose / netifopen requires rtnllock for both. Since the ethtool IOCTL path became rtnl-optional for...

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 ...
