In the Linux kernel, the following vulnerability has been resolved: rcutorture: Fix ksoftirqd boosting timing and iteration The RCU priority boosting can fail in two situations: 1 If nrcpus= maxcpus=, which means if the total number of CPUs is higher than those brought online at boot, then...

kernel: rcu: dump vmalloc memory info safely

A flaw was found in the Read-Copy-Update RCU core of the Linux kernel related to how memory information for vmalloc-allocated objects is dumped. Under certain sequences, calling callrcu may lead to the invocation of vmallocdumpobj while holding the vmaparealock spinlock in an interrupt context...

kernel: net/sched: fix lockdep splat in qdisc_tree_reduce_backlog()

CVE-2024-35892 is a vulnerability in the Linux kernel’s network scheduler caused by improper use of the qdisclookup function. This function assumes the global RTNL lock is held, but in the qdisctreereducebacklog function, only a local queue lock is used. This mismatch creates a race condition tha...
