CVE-2026-98300 tcp: Don't call skb_clone_and_charge_r() for close()d listener in tcp_v6_do_rcv().

In the Linux kernel, the following vulnerability has been resolved: tcp: Don't call skbcloneandcharger for closed listener in tcpv6dorcv. tcpv6dorcv no longer calls skbcloneandcharger for TCPLISTEN since commit 073d89808c06 "net: fix data-races around sk-skforwardalloc". However, there is still a...

CVE-2026-98301

The Linux kernel contains a vulnerability in the net: bridge: mst component where the br_mst_set_state() function calls switchdev_port_attr_set() while holding an rcu_read_lock() . This is problematic because the switchdev notifier chain can invoke blocking calls and sleep. The issue is triggered...

CVE-2026-98301 net: bridge: mst: move switchdev call outside rcu

In the Linux kernel, the following vulnerability has been resolved: net: bridge: mst: move switchdev call outside rcu This is a follow-up of one of sashiko's pre-existing bug reports. brmstsetstate calls switchdevportattrset for nonzero MSTIs while holding rcureadlock which invokes the blocking...

CVE-2026-98300

The Linux kernel contains a vulnerability in the tcp_v6_do_rcv() function where a race condition exists between tcp_v6_rcv() and tcp_v6_do_rcv() . A concurrent close() operation can change the state from TCP_LISTEN to TCP_CLOSE , causing skb_clone_and_charge_r() to be called locklessly. This resu...
