kernel: tcp/udp: Fix memleaks of sk and zerocopy skbs with TX timestamp

In the Linux kernel, the following vulnerability has been resolved: tcp/udp: Fix memleaks of sk and zerocopy skbs with TX timestamp. syzkaller reported 0 memory leaks of an UDP socket and ZEROCOPY skbs. We can reproduce the problem with these sequences: sk = socketAFINET, SOCKDGRAM, 0...

kernel: blk-cgroup: hold queue_lock when removing blkg->q_node

A locking flaw was found in the Linux kernel's block cgroup subsystem. When removing blkg-qnode from q-blkglist in blkgfreeworkfn, the code fails to hold queuelock. This missing lock allows concurrent access from blkgdestroyall, leading to list corruption and potential hard lockups...

In the Linux kernel, the following vulnerability has been resolved: mlx5: fix possible ptp queue fifo use-after-free Fifo indexes are not checked during pop operations and it leads to potential use-after-free when poping from empty queue. Such case was possible during re-sync action. WARNONONCE...

kernel: null_blk: Always check queue mode setting from configfs

A missing validation flaw was found in the Linux kernel nullblk driver's configuration handling. A local user with access to configfs can configure a nullblk device with queuemode set to 1 legacy I/O path, which is no longer supported, causing the driver to proceed without proper validation and...

kernel: net/sched: sch_fq: fix integer overflow of "credit"

An integer overflow flaw was found in the Linux kernel network fair-queueing scheduler in the way the initial per-flow credit is set. If a configuration provides an excessively large initial quantum, the credit value can overflow to a negative number, leading to excessive scheduling and soft...
