Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel, which stems from a post-release reuse vulnerability in the sched/psi module...

CVE-2024-35893

In the Linux kernel, the following vulnerability has been resolved: net/sched: actskbmod: prevent kernel-infoleak syzbot found that tcfskbmoddump was copying four bytes from kernel stack to user space 1. The issue here is that 'struct tcskbmod' has a four bytes hole. We need to clear the structur...

CVE-2024-35892

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...

CVE-2024-35985

In the Linux kernel, the following vulnerability has been resolved: sched/eevdf: Prevent vlag from going out of bounds in reweighteevdf It was possible to have pickeevdf return NULL, which then causes a NULL-deref. This turned out to be due to entityeligible returning falsely negative because of ...

CVE-2024-35985

CVE-2024-35985 concerns the Linux kernel vulnerability where the eevdf scheduler could yield an out-of-bounds vlag and a NULL-deref in certain edge cases. The connected Astra/Nessus documents reiterate that reweight_eevdf() could compute vlag beyond the intended bound, since the vlag is used with...

CVE-2024-35892

CVE-2024-35892 stems from a Linux kernel net/sched issue where qdisc_tree_reduce_backlog() was called with the qdisc lock held while RTNL was not held, triggering a lockdep splat due to unsafe RCU usage. The fix switches from qdisc_lookup() to qdisc_lookup_rcu() to safely dereference qdisc data u...
