CVE-2024-26740 net/sched: act_mirred: use the backlog for mirred ingress
In the Linux kernel, the following vulnerability has been resolved: net/sched: actmirred: use the backlog for mirred ingress The test Davide added in commit ca22da2fbd69 "actmirred: use the backlog for nested calls to mirred ingress" hangs our testing VMs every 10 or so runs, with the familiar...
CVE-2024-26740
CVE-2024-26740: In the Linux kernel, the net/sched act_mirred fix uses the Rx backlog for egress→ingress reversals to prevent socket lock deadlocks on certain redirect scenarios. The upstream patch ca22da2fbd69 implements this backlog-based handling; Nessus advisory AXSA references this CVE with ...
CVE-2024-26732 net: implement lockless setsockopt(SO_PEEK_OFF)
In the Linux kernel, the following vulnerability has been resolved: net: implement lockless setsockoptSOPEEKOFF syzbot reported a lockdep violation 1 involving afunix support of SOPEEKOFF. Since SOPEEKOFF is inherently not thread safe it uses a per-socket skpeekoff field, there is really no point...
PT-2024-8421
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.74-syzkaller Description The issue is related to a lockdep splat in the qdisc tree reduce backlog function, which is called with the qdisc lock held, not RTNL. This can lead to suspicious RCU usage. The qdisc...
